Planet (Galaxy 4)

This Earth-like planet had three suns. When the First Doctor visited this world, it was uninhabited and devoid of all life except plants (most likely because it was at the end of its lifespan).

After a Drahvin ship attacked a Rill ship in space, both vessels crashed onto the planet's surface. When the Rills determined that the planet was going to explode soon and that the Drahvins' ship was irreparable, they offered to take the Drahvins with them. The Drahvins instead attempted to steal the Rills' ship for themselves, but were defeated by the Doctor and left behind when the planet exploded. (TV: Galaxy 4)
