Rogue planet

A rogue planet was a planet which wandered through space instead of orbiting a star. Mondas became a rogue planet when it left the vicinity of the star Sol; however, following an indeterminate amount of time it returned to the area of space it had left. (DW: The Tenth Planet, BFA: Spare Parts)
