** A recent hypothesis to explain one of the most mysterious features of Mars (its northern hemisphere is significantly smoother and about a mile lower in average elevation than its southern hemisphere) is that ''nearly the entire northern hemisphere is an impact crater'' from an object slightly smaller than Earth's moon. The same impact might also be the reason why Mars no longer has an oxygen-rich atmosphere, which it likely did a few billion years ago.

The explanation for the lack of an obvious rim to his possible impact crater is that billions of years' worth of additional impacts by smaller meteors has erased it.


* There is a kind of hypothetical orbital superweapon commonly termed "[[https://www.nytimes.com/2006/12/10/magazine/10section3a.t-9.html Rods from God]]" which is literally a rod made from some quite dense metal - such as titanium - suspended in high orbit, ready to be dropped at any time. The kinetic energy accumulated and subsequently released by such an object is roughly the same as a nuclear weapon without needing to worry about all that nasty fallout. The US military has even considered making one for real, called Project Thor, despite the fact such a weapon would violate the Outer Space Treaty.

* ''Literature/{{Safehold}}'' has the ''Rakurai'', a kinetic bombardment weapons platform orbiting the planet programmed to destroy any place which reaches a certain technology level in order to keep the planet in MedievalStasis. The LostColony's founders used it to destroy the enclave of the people who disagreed with their GodGuise. One of the protagonists' main issues is finding a way to somehow get rid of the platform.

Not content with space-age insurance fraud, he wants to time the explosion so the station will land in Washington, destroying all the government's evidence of his ''other'' criminal activities.

** As mentioned a few examples above, indiscriminate planetary bombardment with asteroids or [=WMD=]s is called "The Heinlen Maneuver" in-universe. It is also worth mentioning that while it may specify ''orbital'' bombardment, many characters on both sides are shown as being understandably antsy about even ''accidentally'' hitting an inhabited planet with an unlucky shot during a space battle (the same concern, in inverse, has at times forced defensive forces to fight at a disadvantage, unwilling to use defensive platforms in orbit over their own planets first lest they force the enemy to return fire). A sizable part of this is due to the Eridani Edict, in addition to many of the officers on both sides of the conflict being good.

As a bonus, the resulting dust cloud would also slightly lower the global temperature, staving off climate change for a few years. The author goes into great detail to describe the sheer destruction such an act would cause. Fortunately, the US learns of the attempt and manages to use nuclear missiles to divert the asteroid.

Furthermore the megalomanic emperor of Earth utilizes a magnetically coupling/decoupling asteroid to threaten Earth.
* The moon-based rebels in the Creator/RobertAHeinlein book ''Literature/TheMoonIsAHarshMistress'' blackmail Earth for independence with moon rocks catapulted from the moon to Earth, resulting in an impact equivalent to a 2 kiloton nuclear bomb. (These are actually the ''good'' guys, waging war against an oppressive government.) This sequence is referenced or repeated in many, many space operas. This is also given a ShoutOut in an ''Literature/HonorHarrington'' novel, as the "Heinlein Maneuver".
** A minor subversion, in that they don't actually target people--[[spoiler: rather, they mostly target uninhabited areas near large population centers, for intimidation value, and a few military bases. The de facto leader of the Lunar rebels even admits that the whole thing is a bluff: if they used one of their rocks to destroy a major city, the people of Earth would never accept their independence, instead demanding that the lunar colony be exterminated. Nevertheless, a large number of people die in the initial round of bombardment, after [[TooStupidToLive going to scheduled impact sites to observe what the government insists will be harmless events]].]]
* Creator/LarryNiven and Jerry Pournelle wrote ''Literature/TheMoteInGodsEye'' with this trope in mind. The newly-discovered planet has been bombarded by asteroids in an uncountable number of wars over the entire history of the aliens. The solar system has reached the point where all the remaining asteroids and comets have been moved to stable orbits where the the cost of rocket thrust is too expensive to use them for planet smashing.



* This trope is best summed up with Jack [=McDevitt=]'s book ''Moonfall''. The dust jacket explains thusly: "A comet is coming. It is going to hit the Moon. And the Moon is going to fall. ON US."
* The eponymous ''Newton's Cannon'' in the first book of J. Gregory Keyes' ''Age of Unreason'' series [[spoiler:is actually a comet King Louis XIV's royal alchemists have drawn down from the heavens, without quite realizing the holocaust they are about to unleash]].

The rebels also destroyed the Martian moon Phobos to prevent it being used as a weapons platform by Earth's multinationals, which led to humongous fragments of the moon bombarding the planet's equatorial regions, just to add icing to the cake of the space elevator's fall. And they even strapped a bunch of rockets to an asteroid that they'd christened Nemesis and pointed it at Earth just to make a point (although it was easily intercepted and diverted). There's a reason they liked Paul Bunyan folklore on Mars: it's because they did everything ''big''.

The impact was so powerful and devastating that the debris launched from the earth formed the moon, as well as giving the Earth its axial tilt. Fortunately, nothing was alive at the time.

*** [[OurOrcsAreDifferent Orks]] ([[CrazyAwesome naturally]]) take this trope to an utter screaming extreme. Their "Roks" are asteroids converted into crude spacecraft, which are sometimes outfitted with troop compartments, retrorockets, and cantankerous force fields, then hurled at a planet as an enormous DropPod. If the landing systems work and a horde of Orks boil out of their space-dropped fortress, that's great -- and if everything goes wrong and there's a massive explosion, that's just as good! Warlord Ghazghkull Mag Uruk Thraka took this one step further and outfitted the Roks he used in the Third War for Armageddon with [[TeleportersAndTransporters "Tellyportas"]], allowing endless waves of reinforcements, including [[HumongousMecha Gargants]], to swarm out of the Roks without further need for troop landings. And it's been even worse than that before, as [[Literature/TheBeastArises The Beast]] had entire ''moons'' customized in such a manner and was more than ready to drop one on Terra.
