aka: The Asteroid Thicket
Leia: You're not actually going in to an asteroid field?In science fiction movies and TV, asteroids form a vast, hyperkinetic, obstacle-strewn Death Course: Enormous rocks spin like tops and whiz around all over the place, frequently even smashing into each other. Trying to navigate one is like asking a chicken to cross a busy Los Angeles freeway during rush hour: Small nimble spacecraft flown by skillful Ace Pilots (i.e, the protagonists) may be able to slalom through without getting reduced to space dust, but any pursuing enemy fighter ships will get picked off one-by-one by giant, malevolent space boulders. Any capital ship who can't just blast a path through them with its Wave Motion Gun will have to rely on their Deflector Shields to bounce the rocks off. It's unfortunate that Real Life asteroid fields, while they do exist, don't have such a flair for the dramatic. Real Life asteroids are strewn much farther apart from each other; so far that the chance of even seeing one (let alone crashing into one) is pretty much nil. Scientists have sent space probes through our solar system's main asteroid belt for decades, and haven't lost a single one in the process. Moreover, a truly violent asteroid thicket, in Real Life, would simply dash itself to bits in a short period of time. Also, due to gravity, even dust will be attracted to itself; close rocks will probably merge. While obviously no first-hand data is available about asteroid fields in other star systems, everything we know about physics tells us that they'd probably differ little from the ones in our own solar system and would be nothing like typical sci-fi depictions. Conversely, planetary rings are (relatively) much more sparse in fiction than real life — dense. Voyager 2 flew through Saturn's G ring — one of the fainter rings — once, at an angle, and there was "lots of evidence of micrometeroid hits" on the quite small 4-meter diameter probe, and the Cassini spacecraft has used its antenna as shield when crossing the same ring during their mission at Saturn. However, aspiring SF writers should know that these planetary ring systems are mostly made up of ice and rocks 0.01 to 10 meters across. A subtrope of Artistic License – Astronomy, Space Does Not Work That Way and Sci-Fi Writers Have No Sense of Scale. Compare Space Clouds, a trope about the similarly unrealistic portrayal of nebula in fiction; also Vulcan Has No Moon for when objects in space are visible in locations where they make no sense (either due to the science or due to pre-established canon). Also compare Conveniently Close Planet - an Asteroid Thicket could be considered "frustratingly close asteroids". A spaceborne equivalent to an Aerial Canyon Chase will take place in one. If there are Asteroid Miners here, they're going to have hazardous lives.
Han Solo: They'd be crazy to follow us, wouldn't they?
Leia: ...you don't have to do this to impress me.

Anime and Manga
- In the second season of Space Battleship Yamato, Yamato attempts to elude the Earth Defense flagship Andromeda by flying at high speed through our solar system's asteroid belt. (To his credit, Captain Gideon of the Andromeda simply flies around the asteroid belt and is waiting for our heroes on the other side in a rare instance of writers remembering that space has more than just 2 dimensions.)
- The "Cemetery Belt" in episode 6 of Heroic Age.
- Mobile Suit Gundam does this with the Corregidor Shoal Zone, a collection of debris from decades of asteroid processing for space colony construction that have aggregated around a LeGrange point. It's a bit more plausible than most examples, as it's relatively young by astronomical standards and it's in a much tighter orbit around its centre of mass than a conventional asteroid belt. Still, while the rocks don't come whizzing out at passing spaceships, there are chunks big enough for Humongous Mecha to hide behind, when collisions due to mutual attraction should have reduced them to gravel years ago and they're dense enough to make navigation somewhat difficult, though not to the point of Wronski Feint-ing.
- Transformers Headmasters abused this in the episode "My Friend Sixshot"
- Starship Girl Yamamoto Yohko episode 5.
- Episode 6 of Super Dimension Fortress Macross used the "rings of Saturn" variation.
- The "rings of Saturn" variation also provided one of the most memorable setpieces for Macross: Do You Remember Love. Hikaru and Minmay steal a trainer Valkyrie for a joyride through Saturn's rings, which includes flying through a crapton of debris at one point, culminating in Hikaru kicking off some of the ice and debris from the ring to create a rainbow in space. The rings are also dense enough for a Zentradi warship to hide within them to capture Hikaru, Minmayu, Roy, Misa and Kaifun.
- Galaxy Express 999 episode 3 depicts our solar system's asteroid belt this way. Granted, the series runs on Rule of Cool, but the asteroid field isn't some futuristic device designed to look like an old-fashioned inaccurate sci-fi asteroid field... it just is an inaccurate sci-fi asteroid field.
- In Cowboy Bebop, Earth is surrounded by an incredibly thick asteroid field. It was born when an experimental jumpgate exploded near the Moon, and a good third of it blasted into pieces, raining down into Earth's gravity field. And daily meteor showers because of it.
- In Star Ocean Ex, Admiral Kenny's ship exits warp into the middle of one. Justified, in that it's the result of the Big Bad's last planetary visit.
- Irresponsible Captain Tylor. The entire fleet is trying to destroy the Soyokaze, which is on a private mission to rescue their captain. Ahead lies an asteroid field, their only means of escape. They ask What Would X Do? and go full speed ahead, proving that the Soyokaze is indeed just as lucky as its captain.
- In the Marvel Transformers Generation 1 comic, our solar system's asteroid field is portrayed in precisely this manner; in fact, the Ark's mission was to destroy a bunch of asteroids so that Cybertron could pass safely through.
- The trope is turned Up to Eleven in 52; apparently the thicket that Adam Strange, Animal Man and Starfire are stuck in has a diameter measured in parsecs. This is handwaved with the explanation that it is not a natural asteroid field, but that comes nowhere close to explaining the sheer amount of mass that is present
- In Plan 7 of 9 from Outer Space, a news report tells of a protocol droid being prosecuted for running a gambling racket, in which he falsely stated that the odds of successfully navigating an asteroid field were 3,720 to 1.
- Star Wars:
- In Star Wars: The Empire Strikes Back, Han, deprived of his hyperdrive, has to slalom through densely packed asteroids to evade an Imperial fleet. This is echoed in Attack of the Clones when Obi-Wan is trying to evade Jango Fett in a planetary ring.
- The unreality of the Empire Strikes Back sequence is lampooned in this Irregular Webcomic!. See also the page quote.
- In A New Hope the "asteroids" are fragments of Alderaan, which has just been destroyed.
- Titan A.E. had the characters flying through a giant ice field. There are a lot of the giant ice shards smashing into each other, which at the rate they were going, they should have reduced the entire ice field to ice cubes within a few years.
- Variation: Instead of an asteroid field, Galaxy Quest has ships traveling through a space minefield. Which makes far more sense because, as a minefield, it's supposed to kill whoever enters it, and the mines were more or less stationary until a ship got close enough to set off magnetic sensors, and close enough together that the ship had trouble staying away from them.
- Meteor shows Earth's solar system's own asteroid belt being like this, with two large asteroids close enough that when one gets hit by a comet, a spacecraft orbiting the other gets destroyed by the debris.
- The lunar shuttle in Airplane II: The Sequel encounters a ridiculously dense asteroid belt after it goes off course. Made doubly ridiculous because of the way they're going: know of any asteroid belts between the Earth and the Sun?
- In the 2011 film Green Lantern, the Green Lantern leads the Big Bad through a classic asteroid thicket. There then follows a questionably plausible sequence involving the sun. Also, the solar system is apparently ridiculously small.
- Armageddon explains the cloudburst of meteorites as the result of a comet passing through the asteroid belt and bouncing shrapnel into Earth's vicinity and knocking one "the size of Texas" towards Earth. This is wrong because a single comet could not collide with so many asteroids and conveniently shove them in the same general direction. Enough shrapnel was knocked out of the asteroid belt to keep Earth in a 'shooting gallery' for 18 days.
- Averted in 2001: A Space Odyssey. While passing through the asteroid belt Discovery passes within visual range of one asteroid. They deliberately chose their route to bring them close enough to make observations of that asteroid.
- Averted and explained in The Martian Way by Isaac Asimov, who says that perhaps the spaceships didn't have to waste propellant to go around the asteroid belt, since, while on map it looks like a swarm of insects, it would take real stroke of bad luck in order to hit a rock.
- Asimov's first published story, Marooned off Vesta, embodies this trope; but as explained in the 2001 example above, this is Science Marches On.
- In the short story "Feminine Intuition", important information about the location of the nearest planets suitable for human colonization is being transported via an aircraft along with the experimentally intuitive robot which calculated the locations. The aircraft is hit and destroyed by a meteorite. Because of how improbable it is, the characters speculate as to whether some higher intelligence orchestrated the meteor strike to keep Earth from learning about their alien neighbors. The odds against this happening are astronomical and in fact compared to the odds of guessing the location of planets to colonize in the first place (which is why they built an intuitive robot to do it).
- Robert A. Heinlein said the same thing in Farmer in the Sky when the narrator observes that the 'old pile drive' ships used to 'plow right through the asteroid field and none of them was ever hit enough to matter', though the universe had a belt more densely packed than in Real Life due to Science Marches On. Nevertheless, he had the Mayflower bypass the Asteroid Belt, to avoid even that tiny chance. Nevertheless, the ''Mayflower'' was hit.
- Similarly, in Heinlein's other Young Adult novel Space Cadet, the captain of the Space Patrol ship Aes Triplex is not concerned about colliding with an asteroid while searching for the missing Pathfinder. However, as above, the Pathfinder was also holed by a meteor with the loss of all hands due to Explosive Decompression.
- And in The Rolling Stones the book takes care to note that the asteroids are far enough apart that the risk of being hit by one is infinitesimally small. Nevertheless The Rolling Stone takes precautions anyway when they enter an unusually dense field that's a haven for miners. Averted in that nothing happens to the ship.
- Justified in Tobias S. Buckell's Halo novel The Cole Protocol. The Rubble is explicitly said to be very unusual, the asteroids having been tethered together, and is kept stable by constant adjustments controlled by an AI.
- Further justified because the asteroids are Trojan asteroids orbiting a gas giant, and each individual asteroid is relatively small.
- The Halo franchise is actually pretty good with asteroid belts as a whole, other than the example in Halo: Reach seen below. The Kig-Yar home system, Y'Deio, is home to a massive asteroid belt that is stated to be abnormally dense (though not to the extent of most examples of this trope, as it has been stated in Mortal Dictata that it actually takes a realistic amount of time to travel between asteroids even with Kig-Yar and Covenant starships). In Real Life, the Y'Deio system is actually a real system, with a different name of course. The system's asteroid belt is notable for being unusually massive and dense, further justifying this example.
- The Eridanus asteroid belt, depicted in The Fall of Reach and First Strike, is also another aversion to this trope. Although The Fall of Reach comic strangely depicts smaller asteroids around Eridanus Secundus (an asteroid within the asteroid belt that is colonized by the United Rebel Front) unrealistically close to each other.
- Subverted in Allen Steele's A King of Infinite Space, where the protagonist claims to expect the asteroid field to mirror his recollections of The Empire Strikes Back, only to discover the scientific reality of the asteroid field.
- Justified and lampshaded in Crusade by David Weber. It first comes up in the context of a closed warp point (a warp point without a significant/detectable gravity field) that happens to exist in the middle of an asteroid belt, which led to the immediate destruction of small ships transiting due to collisions - a situation immediately stated as freakish and unique. One chapter later, an enemy uses an asteroid cluster in a different star system to hide a fleet, while musing that only in a handful of clusters do "conditions even approach those... in popular entertainment."
- From the Star Wars Expanded Universe:
- In Timothy Zahn's Vision of the Future, when the Wild Karrde goes through an asteroid field, Karrde notes that it's more dense than most his crew has encountered, as they have to shoot down asteroids more or less constantly. Zahn, as a general rule, knows quite well how space works and writes accordingly. But Asteroid Thickets are the one thing that showed up in Star Wars and could not be explained or handwaved, so he uses them like anyone else.
- Luke Skywalker and the Shadows of Mindor features Luke and his task force making plans to attack Mindor. This planet had a sister planet very near it not at all long ago, but during a superweapon testing the sister planet was destroyed, and the debris was largely pulled around Mindor in a configuration that was too unstable to be called an orbit. This resulted in the planet becoming largely uninhabitable and the space around it acquiring an "asteroid storm"; capital ships appearing in it had a one-in-fifty chance of being hit by a big rock immediately, increasing incrementally as time went on.
- Asteroid thickets come up once in the X-Wing Series, as the X-wings try to get through asteroids to an enemy ship. The enemy actually had a strategy for this situation, which was to shoot the bigger asteroids, which would destroy the fighters which are hiding behind them on their way to the big ship. Even though a pilot realized this before it happened and called them off, two were taken out on the retreat by, yes, unavoidable giant space rocks.
- There's an asteroid belt near Ithor in Galaxy of Fear thick enough that tiny ships called Starflies are designed to travel through it. It also has space slugs. When flying a Starfly to rescue her brother, Tash has to rely on The Force and the Improbable Piloting Skills it gives her to get through. A pair of asteroids actually slam into each other in front of her, becoming a hail of smaller particles.
- Completely averted in Larry Niven's Known Space universe. Larry is well known for Showing His Work. Belters are explicitly described as spending months at a time alone, flying their singleships between asteroids on prospecting runs. He even extrapolates and uses the ramifications in his stories. Not everyone has the kind of personalty to handle that amount of nothing for the length of time that is required to get from place to place. The ones who can't never come back to port. Belter society is made of the ones who can.
- Justified in the vaguely truer-to-Trope Serpent Swarm in the Wunderland system. The Swarm is explained as a planet that recently (in astronomical terms) broke up, and is described as a "crescent" that spans 1/3 of its orbit around the sun. In the "center" of the swarm, the remnant chunks of planet are just barely close enough to fly between without losing your mind from boredom. Still far enough apart that the human rebels against the Kzinti takeover of the system were easily able to spread out and hide themselves in the swarm.
- Future Hope features a cocky, crackerjack space ace whom the author attempts to characterize as the greatest in the solar system by describing how he was famous for being the only pilot to ever safely navigate through the asteroid belt without his navigation tools on.
- It's strongly averted in Stanislaw Lem's Tales of Pirx the Pilot. The protagonist's ship was maneuvering in an asteroid cloud for several hours without actually seeing one asteroid. This trope is also lampshaded when a panicking passenger who doesn't know much about space wonders why the captain isn't trying to evade the asteroid cloud, and then declares the captain insane when he is told the asteroids aren't dangerous.
- Averted in Lacuna. Liao hides the ship in the Solar System asteroid belt and Summer complains about how it's a terrible place to hide because it's so empty.
- The Boneyard in the Star Trek: The Genesis Wave series. The titular wave, an Interstellar Weapon, is launched from a base concealed within it.
- In The Hot Gate, it's noted as unusual that another star system has a dense asteroid belt, contrasted with the comparative emptiness of Sol's belt.
- Lampshaded in The Astronaut's Apprentice by Philip Threadneedle. Before they reach the Asteroid Belt, Grandpa tells Bradley that you can jump from one asteroid to the next, or swing between them on ropes. Bradley (who read a book about the Solar System before leaving Earth) refuses to believe this, and tells Grandpa that the asteroid belt is "mostly empty". However, when they reach their destination, it turns out that Grandpa is correct.
- The StarCraft novel Flashpoint features the Kirkegaard belt, known colloquially as the "Kick-You-Good" belt. The Moebius Foundation maintained a cloaked research base there accessable only by a specific and very slow route. Arcturus Mengsk's fleet decides to simply blast their own shortcut.
Live Action TV
- Battlestar Galactica. Guilty as charged. Rather surprising given that it's usually relatively accurate when it comes to astrophysics.
- The Blake's 7 episode "Mission To Destiny" features a space storm that appears as an asteroid thicket. An interstellar one.
- The pilot (episode, not the character Pilot) had an asteroid thicket.
- In the Peacekeeper Wars wrap-up mini-series, Braca leads a fighter squadron through a planetary ring in order to strike at the rear of the Scarran battle fleet. Plausible (not the thicket) in that radiation would keep the squadron's approach masked from enemy sensors.
- The premiere episode of Lost in Space, "The Reluctant Stowaway", featured the Jupiter 2 being pummeled by asteroids as it drifted off course into the belt.
- The 2007 4th season premiere of Stargate Atlantis has Atlantis, shot into space in the previous season, having to make its way through an asteroid field. Sheppard, McKay, and a team have to shoot the asteroids into pieces to clear a path. Sheppard, trying to reassure McKay, compares it to the video game Asteroids. McKay responds, "But I was terrible at Asteroids! I think I actually scored zero once!".
- Star Trek:
- The Star Trek: The Original Series episode "Mudd's Women" shows the Enterprise chasing Harry Mudd's stolen ship through an asteroid belt (at relativistic speeds) where the asteroids are seen to zip past the Enterprise (as seen by the bridge screen that Kirk is looking at). The asteroids appeared to be spaced apart from each other at considerable distance rather than the traditional Star Wars-type asteroid thicket.
- In the 7th season episode "Genesis" of Star Trek: The Next Generation, the Enterprise sends a shuttle craft into an asteroid field because it was too dense for the Enterprise to go in safely. It was mentioned that the asteroid field was unusually dense though. This was by far the least significant scientific inaccuracy in this episode, where the crew 'de-evolved'.
- Star Trek: Deep Space Nine manages to avert this in the overall setting. The wormhole (and station) are both located in the system's asteroid belt but all the shots of the station and wormhole don't show any asteroids in the immediate area and they're never mentioned as a navigational hazard.
- In a 7th season Star Trek: Deep Space Nine episode, Odo tries to hide from some Jem'Hadar by flying into a dense Kuiper Belt, which aside from trading comets for asteroids, is still a classic Asteroid Thicket.
- Part of the race course in the Stargate SG-1 episode "Space Race" goes through what appears to be an Asteroid Thicket composed of house-sized chunks of ice.
- There's one in the "Asteroid Threat" mission of Star Trek: The Next Generation. Possibly justified since they may be the debris from the lone giant asteroid they just blew up.
- Traveller sometimes hasthem, but this is justified since they are the remains of destroyed planets.
- The Star Wars-Risk boardgame used an impenetrable asteroid field to represent planets destroyed by the Death Star, rendering travel in the region problematic.
- Twilight Imperium features asteroid belts that take up the same amount of space as a star system and pose a serious problem for the movement of certain classes of starships.
- The Asteroid fields in Battlefleet Gothic are an egregious example, probably caused by the target audience expecting "terrain" to fight around. The effects of asteroid fields are thus: Anything unguided (a space hulk, torpedoes and so on) are automatically destroyed upon entry. Attack craft have a 1 in 6 chance of destruction and full space ships (from escorts to capital ships) must take a command check, and if failed can take crippling damage in a single instance.
- Eclipse Phase actually manages to avoid this. There are asteroid fields, but they're exactly as they are in reality.
- In Star Fleet Battles, asteroid fields are thick enough so that any ship or seeking weapon passing through them has a significant chance of taking damage, possibly enough to destroy it. They also interfere enough with sensors to allow ships and bases to hide within them.
- SPI's Universe DeltaVee rules. Whenever a ship enters an asteroid field it must check for collision (roll speed or higher on a 6 sided die to avoid). The faster a ship traveling, the greater the chance for a collision. At a speed of 6 or higher the ship is certain to hit an asteroid.
- Eureka: 501 Adventure Plots to Inspire Game Masters adventure "Murphy’s Law, Squared". When an out-of-control asteroid enters a debris field on the edge of a solar system it will hit another asteroid unless the PCs can prevent it.
- Starblazer Adventures, campaign setting Mindjammer, adventure "The First Casualty". When an out-of-control ship suddenly appears near Gentility Base it is on course toward the nearby asteroid belt and is likely to suffer a catastrophic collision if it enters it.
- The Grinder around Oerth in the Spelljammer setting. Of course, the Spelljammer universe is not intended to reflect real space in any way.
- In Rocket Age the Asteroid Belt is full of fast moving debris, making mining incredibly dangerous. Not that anyone lets that stop them.
- These show up scattered throughout the sector on the more interesting settings in Artemis Spaceship Bridge Simulator.
- The X-universe series of games plays this trope straight 90% of the time; one sector has about 80 asteroids (about 1-2km in diameter) crammed into an area about 80km on each side. Most sectors have much lower concentrations, but even those have 3-10 asteroids in a sector, which have only 80-200km between the two pairs of jump gates.
- The classic arcade game Asteroids, where the asteroids just go through each other: either they cheat, or their dodging skills make them smarter than the player. Clearly the player's ship is actually a huge arrow-shaped tower.
- The first set of starship battles in Ratchet & Clank: Going Commando take place in such a region, though again this may be justified by the fact that it seems to be gathered around a possible mining station.
- The Meteo area in the Star Fox games. "Use the boost to get through!"
- The classic Space Sim Wing Commander and Freespace both used this trope, the former as a Death Course for fighters. The latter creates a very distinct mix of infuriating and awesome by making the asteroids too slow and clumsy to be a threat to fighters, then having missions where a desperate capital ship plows through them and has its small craft play point defense against the Malevolent Asteroids that continually appear out of nowhere to converge on the target ship.
- To elaborate, in FreeSpace, collisions (including with asteroids) don't do that much damage—you'll take some hull damage from the impact, but unless your ship is already about ready to fall apart, you'll be mostly fine. But capital ships are big, the asteroids are numerous, and the damage from asteroid hits will add up fairly quickly if you aren't diligent in blasting them apart before they hit. Made worse by the fact that these missions usually also involve some enemy or another attacking the ship at the same time…
- FreeSpace 2 makes asteroid defense missions especially infuriating because of a bug in the game's engine that causes big ship turrets to not shoot at incoming asteroids (despite one mission briefing explicitly stating that the turrets will shoot at asteroids, "so we shouldn't have too much trouble"). When the campaign from the original FreeSpace was ported over to the new engine by fans, the otherwise-faithful port ended up making these missions much harder than they were originally.
- Freelancer carefully examines this trope. First, due to their thickness, most asteroid fields in the game are hiding places for criminals. Second, also due to their thickness, several asteroid fields are also suitable for mining operations. Third, some of these asteroid fields are actually made of junk (one of them is even a minefield!). And finally, the spacecraft manufacturers must be very aware of the difficulty of navigating these places by hand, because in order to get across an asteroid field, you just have to set a waypoint to your target, press the Go To button, and the computer will do the slaloming for you.
- The Escape Velocity series (plays like Privateer, looks like Asteroids) has immensely thick asteroid belts, but ships cannot collide with them. Their purpose is simply to interfere with weapons fire (though they can also be mined in the third game).
- In Homeworld, one mission puts you right in the center of a swarm of malicious asteroids, your objective being to get your smaller ships out of harm's way while blasting apart asteroids that are about to collide with the Mothership. There's a margin for error in that the Mothership can handle a few hits, but it's still not quite as easy as it sounds.
- In another mission, a large asteroid is deliberately steered into the path of the mothership (via a huge engine built into the asteroid's "back"), as it cannot change direction when in hyperspace, and will automatically exit hyperspace when a potential collision is detected.
- The various Star Wars-based space sim/shooter games tend to have at least one mission with a whack o' asteroids, probably in deference to Episode V, though in this case the asteroids tend to be much less harmful in and of themselves (though they might prove to be excellent platforms for a starfighter hangar, well-defended space-base, or weapons turrets).
- Empire at War uses them as well; large ships will usually fly around them to avoid losing shields.
- Stage 3 of Shadows of the Empire has the Outrider trying to escape from the Empire in an asteroid field, but Dash leaves the piloting to Meebo, so the player really doesn't even have to think twice about them.
- In the first Rebel Assault game, the player (Rookie One) is chased through an asteroid field, similar to the scene in The Empire Strikes Back. Towards the end of the run, a torus-shaped (doughnut) asteroid appears. Genre Savvy players know that, since this is Star Wars, fly directly through the center of the asteroid. The pursuing TIE fighters will be clipped by the asteroid as it spins past the point where you get through.
- The PS3 downloadable title Super Stardust HD has asteroids that swoop down, and then start orbiting around the planet you're guarding. This appears to be because of an incredibly powerful planetary shield whose existence is for some reason entirely dependant on the existence of your ship. The backstory explains that the asteroids are being thrown at those planets by the attacking aliens to distract you when they attack.
- The MMORPG EVE Online suffers from this trope in that of the 5000+ solar systems, a large majority of them have at least one "Asteroid Belt" orbiting a planet, and some have upwards of 20 or 30. This alone isn't enough... the asteroid belts themselves are composed of a belt maybe 100km from end to end with asteroids of various mineral types densely packed together; in some cases the asteroids are so large and so dense that avoiding their collision boxes is an exercise in futility. This is mostly due to decade-old design decisions. The asteroids are used for mining by players, and going from one rock to the other in a realistically sparse asteroid field in clumsy mining vessels would be very annoying to say the least. Various modifications and reforms to asteroid belt realism and the interactivity/fun of mining in general have been floated by CCP over the past few years, but so far they appear to be on the back burner. Finding a fix that doesn't destroy the economy is bound to be problematic.
- Avoided in the classic 1984 space simulator Elite and its sequels. Whereas the first game had several classic examples of artistic license such as no star system containing more than one planet and one sun, it did, more or less, bang asteroids on the head. As the game was randomly generated, it was not unusual for players to never come across an asteroid ever when playing the game!
- In the sequel Elite: Frontier star systems were more realistic, usually having several planets of various sizes.
- The fourth Elite game, Elite: Dangerous, mostly goes the realistic route, where the planetary rings (namely Saturn-like ones) are dense, and the belts around a star are very diffuse with a few pockets of a handful of close asteroids.
- Averted in Super Metroid and Metroid Fusion: the Ceres Research Lab is stationed in the middle of an asteroid field (possibly the Asteroid Belt, given the name of the station) and the asteroids therein are completely static in relation to one another, if densely packed. In the sequel, Samus only crashes into an asteroid because the X Parasite infection had knocked her out.
- Averted in Darkstar One, where navigating an asteroid field is pretty easy, with the asteroids being large, slow and very dodgeable. The only marginally difficult part is entering into special asteroids to collect pieces of the Darkstar.
- Justified in Dead Space, as the thicket is actually the debris kicked up by the mining ship the game takes place on pulling a continent-sized chunk out of the planet it's orbiting.
- Similar to the Dead Space example, Knights of the Old Republic II: The Sith Lords starts out in a thicket created by a mining accident causing a chunk of the planet to explode and be ejected into space.
- Doomsday Zone from Sonic & Knuckles teaches us that there's a dense asteroid field in Earth's orbit. Who knew? Barely room to fit a hedgehog between the rocks, even.
- In the classic TI-99/4A game, Parsec, asteroid belts are unusual indeed. The game is a Horizontal Scrolling Shooter, where you fly a ship around the planet. Despite this fact, you encounter asteroid belts regularly! And each "belt" contains an identical pattern of asteroids, starting with a huge column of rocks coming at you. Each subsequent belt comes ever faster, which suggests they should have crashed into each other ages ago.
- Edge of Chaos has this in spades. The asteroids will blow up like bombs if you shoot at them a few times. There was even a mod that turned this up to 11 by making the asteroids fly around at ridiculous speeds, pelting everything like a space hail storm.
- Then there's also Zanac and Zanac Neo. Thick asteroid field can be seen in arer 5 in the original and thicker one is in the second stage of Zanac Neo.
- In Evochron Legends most asteroids are clumped together, with 10-20 asteroids in a 10x10x10 KM area. Some solar systems however, have asteroids very thinly spread out across the system.
- Mass Effect averts the dense nebula version; the Horse Head Nebula is home to various chunks of the story and sidequests, and its perfectly livable. The Serpent Nebula the Citadel sits in appears to follow this straight, but the Codex entry lampshades the improbability of such a dense nebula, notes that it makes navigation (and therefore, external attack) extremely difficult outside the perimeter of the Citadel's mass relays, and cites an in-universe theory that the Citadel itself creates and maintains the nebula artificially with its waste disposal systems. Oddly, the Serpent Nebula can't really be seen from the surface of Bekenstein, a habitable planet some distance away from the Citadel; it is, perhaps, so close to the edge of the nebula that the gasses have thinned out.
- That bit about the Citadel becomes Harsher in Hindsight Foreshadowing when it is revealed the Citadel is basically a trap set by the Reapers.
- The end sequence of Mass Effect 2 also manages to create an awesome asteroid-maze sequence with fewer scientific issues. When the Normandy goes through the Omega-4 relay, it emerges in a frequently-replenished junkyard of wrecked ships that have passed through without the proper preparations and run into things.
- Conquest Frontier Wars has plenty of these, conveniently on the edges of map, these thickets slowed down ships travelling though them. The manual explains that the fields in the game are just representations of what is actually going on, and that the ships slow down in order to navigate through the field (the slaloming is not actually shown in the game). The nebulae are even weirder with their strange abilities (knocking out shields, decreasing weapon effectiveness, hiding entire fleets, etc.).
- In Star Control, every single space battle, no matter where it occurs features a ridiculous amount of ship-sized asteroids. They are continually spawned to maintain a stable number, never lose momentum, and are sometimes spawned aimed directly at your ship. Fortunately, they can't actually hurt your ship, unless they bump it into the planet (another feature that's always somehow present regardless of where the battle takes place). They can be a major nuisance for the slower ships that need to spend quite some effort to get going in any specific direction.
- If you fight a battle in an asteroid belt in the Space Empires games, they tend to damage missiles and fighters heavily. They can even damage capital ships in strategic movement sometimes.
- In The Babylon Project, the raider bases are generally located here.
- Halo: Reach's introductory cinematic at one point passes through a very dense ice belt. A collision between two ice bodies can actually be seen as the camera moves onward.
- Averted in Master of Orion II, where battles in asteroid fields don't actually feature any asteroids. However, blowing up a planet with a Stellar Converter and then rebuilding it with a colony in the same system can result in a larger and richer in resources planet than the original. So, apparently, a planet is more than the sum of its parts. Which actually makes sense as normally the core is filled with dense elements (more valuable ones, like gold or rhodium)—rebuilding the planet from the debris doesn't have to be done in the same way, causing more resources to be on the surface and without millennia of gravitational compression the size could be larger at first (although not the mass).
- In the original game, however, the tactical battle map in some systems had squares randomly occupied by asteroid patches. Ships can't pass through them, and any missile clusters trying to pass through one of those squares get their count reduced, potentiallynote turning a One-Hit Kill salvo into one that does little more than tickle a ship's passive defenses (shield/armor).
- In Millennium Return To Earth, the first probe to be sent to the Outer Solar System gets destroyed while passing through the Asteroid Belt. The technicians then apologize for not anticipating how dense the field is and claim the next probes and ships will fly above or below the belt. Interestingly, this does not add to the travel time. The Belt is also used for Asteroid Mining.
- In Space Quest V: The Next Mutation, the crew of the SCS Eureka is forced to evade the SCS Goliath and hides the ship in a nearby asteroid field. While the asteroids are not shown moving or colliding, they do spin quite fast and appear to be close together. When Roger is forced to go EVA to rescue Cliffy, there is a mini-game that requires the player to navigate the EVA pod. However, the asteroids are only in the background and do not pose a danger.
- Most of the gameplay in Starscape involves shooting moving asteroids and collecting the resources that appear in order to research and build better weapons and ships.
- Ships passing through asteroid fields in Haegemonia: Legions of Iron get slowly damaged, possibly from micrometeorite strikes.
- Area 7 of Super Aleste.
- Arod in Meteos. It's somehow developed intelligent life of its own adapted to the asteroids' extremely low gravity and total lack of atmosphere. While the asteroids are so close together that its snake-like inhabitants like to jump from one to another, it is still one of the more realistic portrayals in a game series with purposely unrealistic and physically impossible worlds.
- In Galactic Civilizations II: Justified in the representation of asteroid fields on the galaxy map (what else would you use as a map symbol for an asteroid field?) - but not justified in the cutscene when you investigate your first anomaly.
- The introductory zoom-scene from Contact shows the solar system's own asteroid belt as one of these. The scene is otherwise fairly accurate on scales, however (except for the distance of radio transmissions). The team that created the opening said they did it on purpose partly for Rule of Cool and partly because most people would think a fully accurate portrayal of the entire sequence would look "wrong."
- The asteroid field from Gradius V serves as the current page image.
- Sega's 1981 Astro Blaster game has the player's ship flying through a meteor shower at the end of each level.
- Super Robot Wars uses Asteroid Thicket as a terrain, an equivalent of a forest where a unit can hide in and gain defense and evasive bonuses.
- Played straight in the otherwise realistic game Star Citizen for purposes of the Rule of Cool.
- No Man's Sky features this trope in full effect, and allows players to destroy sections of them to create such things as pathways for easier navigation.
- Space Engineers is set within an asteroid field, where you mine asteroids within space-walk distance from each other. Pre-release videos showed even denser fields - to the point of making one of the default ships difficult to fly without shearing the engine nacelles off - though the density was toned down for release, likely for performance reasons.
- This is actually averted in Video Game/Rodina, where the asteroid field is much closer to what you would find in real life, with them being too far apart to see without the aid of your radar.
- Drive. Skitter loses a pursuing Continuum ship in one. Subverted, in that it's not your typical Space Is an Ocean thicket - they could easily go around it, and it's only dangerous because they're navigating it at FTL speeds.
- Far from Home: For scouting.
- In Parallels, they are the badlands.
- Though we don't actually see any in Commander Kitty, Morris refferences the trope by describing the swarm of Triple-I Skyflies as being "thick as asteroids".
- The Asteroid Thicket in The Empire Strikes Back is, of course, parodied in Darths & Droids:
Princess: Chewie, get up here! We're going through an asteroid field!Han: That's no problem. Just don't hit whatever asteroid might be within a hundred thousand kilometres. They're in nice, stable orbits too, so it's easy to avoid them.Princess: Okay, fine. We're going into a massive region of randomly moving, closely packed, enormous giant space rocks.Han: Gaaaaaah!GM: It's my proudest creation.
- And in the Star Trek: The Original Series parody comic Planet of Hats (also by David Morgan-Mar), Spock's line from "Mudd's Women" that the asteroid belt has a "Schiller rating" of 3 5 is defined as "2^35 denser than a real belt".
- Invoked in the AH.com: The Series episode The Machine, in which Captain Dr. What (whose knowledge of how the universe works is mainly based on old movies) tries to hide from the Vendetta in an asteroid belt, and the most knowledgeable GBW keeps trying to point out that the asteroids are too dispersed for this to work.
- In Pay Me, Bug!, Tyrelos Station is surrounded by the debris from a recently (in astronomic terms) destroyed moon.
- Futurama's episode "A Flight To Remember" lampshades this. Zapp Brannigan deliberately makes a "course correction" to the safe flight of the pleasure cruise to take the spaceship through an field of comets. After several near misses (and one hit), he then pilots the ship directly into a black hole.
- In "Love and Rocket", Leela is having to swerve about like she's driving on ice whilst piloting through a field of asteroids.
- Invader Zim had this in one episode. Zim piloted a ship into the asteroid belt during a dogfight with Dib and it was destroyed by the asteroids. They were, respectively, piloting Mars and Mercury.
- The episode "Little Girl Lost Part 1" of Superman: The Animated Series very neatly and subtly averts this one. While scanning the shattered remnants of Krypton, which have slowly begun forming into an asteroid belt, he receives a distress call from just outside the system. Rather than play "Asteroids" in his protective ship, he simply drops down and ducks under the field to get there as quickly as possible.
- Averted/lampshaded in the Family Guy adaptation of The Empire Strikes Back when Threepio (played by Quagmire) says in the asteroid scene "Sir, the odds of successfully navigating an asteroid field are 2-1!". To which Han (portrayed by Peter) replies "Never tell me the o-oh... well that's not bad. Never mind, let's keep going."
- This happens in the first episode of The Transformers, where going through an asteroid belt causes the Autobots and Decepticons to crash on Earth.
- Star Trek: The Animated Series episode "The Pirates of Orion". The title opponents' ship flees into an asteroid field that consists of a large collection of rocks close together. There are so many asteroids that it's easy for the Orion ship to hide among them.
- In the Samurai Jack episode "Jack and the Flying Prince and Princess," the titular royal figures evade enemy spaceships by maneuvering through a planetary ring system as an homage to the Star Wars films.
- Dogstar: The Valiant is halted by one in "The Quick and the Dog", where the asteroids are no more than a few feet apart.
- Until the Pioneer 10 space probe passed through the asteroid belt, nobody really knew how dense the belt was. Only several thousand big lumps had been spotted up to that time, but there was a well-founded worry that the craft would be peppered with impacts from many small or tiny rocks. Luckily Pioneer (and all later missions that went beyond Mars) met with nothing whatsoever.
- Analyses of identified extrasolar asteroid belts indicate that they are much thicker than our own. Granted that's just the ones that we can see from several light-years away, so there's probably a lot more that are just as dense if not looser than the one in our system.
- The closest this trope gets to real life is companion asteroids, where small asteroids orbit larger ones, sometimes as little as 90 meters from each other. This is generally rare, though, and it would still take appalling luck or monumental idiocy for a spacecraft to impact one.
- There is now evidence that one asteroid actually has its own ring system, which may mean that others could as well.
- In its earlier stages of development, the Solar System had a lot of debris floating around crashing into each other and eventually forming the inner planets. The Late Heavy Bombardment was the final cleanup of this debris by the inner planets absorbing them via impacts, the craters of which can still be seen on the Moon and Mercury (and Marsnote ). However, even this hodgepodge would have been extremely thin compared to its fictional counterpart, with the "cleanup" taking hundreds of millions of years.
- One other reason is that Jupiter and Neptune effectively serve as the giant vacuum-cleaners of their respective regions of the Solar System, thinning out any errant asteroids.
- Planetary rings have large numbers of rocks, though they're generally smaller than what this trope uses.
