* In ''Film/JupiterAscending'', Jupiter's parents are said to have met while stargazing at the shore of Neva in Saint-Petersburg. Saint-Petersburg is in fact overcast during most of the year, and even when the sky is not clouded, stars can't be seen there.

Saint-Petersburg is in fact overcast during most of the year, and even when the sky is not clouded, stars can't be seen there. In addition, in summer the sky over St. Pete never gets dark enough to see any stars - that's the famous "White Nights of St. Petersburg", a phenomenon also well known in other northern locales.

* A very common SpecialEffectFailure in video games is the "bright sky, black moon" effect. Video game designers try to make a moon with variable phases and combine it with an unrealistically bright sky full of Hubble-style nebulae. The moon's dark side, quite realistically black, does not blend well into this sky and sticks like a sore thumb. This defect can be found in:

** ''VideoGame/KerbalSpaceProgram'';

*Also in the D&D splatbook, Elder Evils, the World Born Dead, Atropus, consists of a small rogue moonlet that seeks out planets covered in life and destroys them via bodyslam. The book describes Atropus as having a tiny (planetary-wise) diameter of 700 miles. However, base on the mechanics centered on it, the surface gravity is around 2/3rds of that of Earth's. This means that either magic is making things weird (it is a god's corpse after all) or Atropus is entirely made up of something far denser then lead, giving it a mass more comparable to Mars.

* In ''Film/JimmyNeutronBoyGenius'', Jimmy claims that the Yokian's home planet is in the Orion system, approximately 3 million light years away. The Orion system is actually only 1360 light years away at its farthest estimates, and any star that far away would have to be in a different galaxy regardless.

* There is an energy snack commercial where a basketball player (Lamar Odom) shows off his ability to dunk to the Moon. On his way, he tells Saturn to get out of his way. If we're suspending our disbelief enough to buy that a guy jump to the Moon, Saturn might as well be between the Earth and the Moon. The next guy says he's going to dunk on Pluto. Okay. For all we know, that might be a shorter trip than one to the Moon, in this {{ficton}}'s astronomy.

* Towards the end of Creator/JKRowling's ''Literature/{{Harry Potter and the Order of the Phoenix}}'', in mid or late June, Harry is taking his astronomy O.W.L. and charting Orion. Orion is not visible in the night sky in mid or late June at ''any'' latitude. The same scene also has him looking around for Venus (which is never more than 47 degrees away from the sun) around midnight. Needless to say, he didn't do particularly well on ''that'' O.W.L.. Just as well. Muggles have to be better at ''something.''
** In addition, it never gets dark enough for stargazing in northern Scotland in July.

* A common problem that sneaks in quietly in a lot of science fiction works. In reality, the Earth is orbiting the sun at about 30 km per second, the sun is speeding around the core of the galaxy at about 220 km per second, and the galaxy is speeding through the universe at about 550 km per second.
* A lot of sci-fi works will refer to the distance between two planets as if it was a constant as well, despite the way they are orbiting at different speeds.
* [[WesternAnimation/LooneyTunes Marvin the Martian]] wants to [[EarthShatteringKaboom blow up the earth]] because it obstructs his view of Venus. Just wait a moment... In reality, astronomers would flock to such an event. There is plenty one can learn about both objects when a planet eclipses a star (or another planet).
** A planet eclipsing another is a rare, and quite brief, event that would likely be over in the amount of time Marvin spends plotting about it.

* In the novellization of ''RevengeOfTheSith'', Anakin recalls a visit to a black dwarf star system: ''a frigid dwarf of hypercompacted trace metals, hovering a quantum fraction of a degree above absolute zero''. Even now there are no such objects yet, since they require hundreds of billions of years to cool, and the Universe isn't old enough; and Anakin lived "a long time ago", that's in a universe even younger than ours.

** [[JustifiedTrope Though, to be sure]], it's a trope in the series that "all things are connected", and indeed, one character in ''Literature/AWrinkleInTime'' is herself a former star who blew herself up to fight the cosmic enemy.
* In the 2009 ''Franchise/StarTrek'' reboot/alternate continuity film, the Romulan system is destroyed by the shockwave from a supernova...trouble is, the star shown exploding is an average-looking ''yellow'' Main Sequence star (like our own), which are neither hot enough nor massive enough to generate a supernova. Supernovae form almost exclusively from extremely massive blue-white stars.
** [[spoiler:Finally explained away on ''VideoGame/StarTrekOnline'' as the result of the local BigBad AncientConspiracy.]]

* In the season 6 finale to Series/TheBigBangTheory, "The Bon Voyage Reaction", Raj shows his girlfriend the International Space Station, using a telescope to do so. The problem with this is the ISS orbits the earth every 90 minutes, so it is constantly moving. A telescope's field of vision is ''small'' so you would have to keep moving the telescope to see the ISS or it would whiz by very quickly. [[http://www.nasa.gov/vision/space/travelinginspace/f_skywatch.html The telescope was probably unnecessary anyway because the ISS is usually visible to the naked eye as it moves across the sky.]]
** With today's "[=GoTo=]"-Telescopes (computer-controlled positioning), it IS possible to keep the ISS in view while it's crossing the sky, under magnifications high enough to clearly show the major features.
* Several works of fiction show amateur astronomers viewing meteor showers through a telescope. In fact, a telescope is the absolute ''worst'' thing to view a meteor shower through, since you need as much sky coverage as possible. The best piece of equipment to view a meteor shower? A lawn chair.
** This was actually subverted (intentionally or not) in an episode of ''Series/MalcolmInTheMiddle'', in which a group of nerds attempt to view a meteor shower through a telescope, only to have their fun ruined by Malcom and his brothers throwing food at them. They eventually get their own back, and knock Malcom and his brothers onto their backs, where they then view the meteors.

** The name is technically correct, though: before the Copernican Revolution, the term "planet" was applied loosely to ''anything'' that was bright and moved through the sky compared to the "fixed stars"; thus, the Sun and the Moon were "planets" too (while the Earth obviously wasn't). Even then, the term "planet" was still somewhat vague (Jupiter's moon were initially "planets" upon discovery; the major Main Belt asteroids were planets), and even today there's still no consensus over it (Pluto, anyone?). Basically, any pre-Copernican artifact, text or tradition, such as Ancient Egypt artifacts, calling the Sun and the Moon planets is thus justified.



** In ''Anime/BattleOfThPlanets'', the Spectrans are based in the Crab Nebula.



** Same for the arcade game ''{{VideoGame/Solar Warrior}}''. Jupiter appears as a desert world complete with ''{{Literature/Dune}}''-like worms, likely as a ShoutOut to it.
