Mimas
From Wookieepedia, the Star Wars wiki.
Mimas is the smallest and innermost of seven major moons orbiting the planet Saturn in the solar system, notable for a single enormous impact crater called Herschel.
While an uncanny visual for most anyone, the moon is of particular interest to fans of Star Wars because of its striking similarity to the Death Star. However, this is merely a coincidence, as Mimas was not photographed until three years after the release of the first film, in 1980.
Recently, however, images from the Cassini orbiter have shown Mimas to be more egg-shaped than spherical.
