'''Basic Trope''': A ship the size of a planet or moon.
* '''Straight''': The interstellar ship ''Colossus'' is the size of a moon.
* '''Exaggerated''':
** The ''Behemoth'' is much, much bigger than the solar system.
** The ''Goliath'' is a massive, spaceship that resembles (And about as large as) a galaxy.
** The ''Titan'' is as large or larger than an entire universe.
* '''Downplayed''': MileLongShip
* '''Justified''':
** The ''Colossus'' was constructed by hollowing out a large asteroid, or by attaching freakin' huge engines to an actual planet.
** The ship needs to be that large to generate the power needed for near-lightspeed/faster-than-light travel, withstand the impact of all the random debris it might inadvertently hit along the way, and its large mass is useful for providing natural gravity to keep the crew healthy on long space missions.
* '''Inverted''': The ''Miniscule'', although known as an interstellar ship, is only slightly larger than the pilot.
* '''Subverted''': The ''Colossus'' looks like it is the size of a planet, but it was just an illusion or other trick used to make it seem bigger.
* '''Double Subverted''': The illusion didn't really make the ship seem bigger, it made it seem smaller.
* '''Parodied''': The captain of the ''Colossus'' sees some planets orbiting a sun and decides, "When in Rome..."
** The first shot shows the Colossus as basically a planet with engines attached... until the zoom pulls out and we find it's actually a ''tiny'' spaceship.
* '''Zig Zagged''': The size of the ''Colossus'' is inconsistent. In one scene, it is being maintained after landing on a planet, in another scene, it is big enough to cause a solar eclipse when passing in front of a star and later on the ship is bigger than the Sun.
* '''Averted''': The ''Colossus'' is only 100 meters long.
* '''Enforced''': The executive producer just came from an ArchiveBinge of Creator/DavidWeber's ''Literature/EmpireFromTheAshes''.
* '''Lampshaded''':
** "How in God's name do they even ''move'' that monstrosity?"
** The ''Colossus''' AI yells "YOU ORBIT AROUND ME!"
* '''Invoked''': Emperor Evulz orders the creation of the moon-sized ''Colossus'' as a show of imperial might.
* '''Exploited''':
** The inside of the ''Colossus'' is rife with smuggling, because who can find every nook and cranny in something that big?
** [[ThatsNoMoon The ship is hidden in plain sight as a planet's moon, because who would expect a ship to be so big?]]
* '''Defied''': Government officials ask some engineers to draw up plans for a PlanetSpaceship. Engineers ask government officials what they've been smoking.
* '''Discussed''': [[Film/ANewHope "Look at the size of that thing!"]]
* '''Conversed''': "My WillingSuspensionOfDisbelief took a nosedive when the writers brought out a planet with engines on it."
* '''Deconstructed''': The gravity well of the ''Colossus'' destabilizes any solar system it flies to, [[NiceJobBreakingItHero resulting in some unintentional]] ApocalypseHow for [[RoguePlanet any unfortunate planet or celestial body that gets destabilized]].
* '''Reconstructed''':
** The above destabilization is prevented by a microgravity field around the ''Colossus'' that protects solar systems.
** Alternately, the [[DoomsdayDevice destabilization is the whole point]].
