Unidentified red planet

Little is known about this red planet, found in Indiana Jones's system, except that it was colored crimson, and that it was the closest planet to Indiana Jones' homeworld.

Han Solo and Chewbacca of the Millennium Falcon, having entered this star system while evading the Imperial Navy sometime after the Battle of Endor, passed by this planet before being caught in the gravity well of Jones's homeworld.

Behind the scenes
The planet, alongside three other planets, including Indiana Jones' Homeworld, appeared in the non-canon Dark Horse comic serial Into the Great Unknown, which acted as a crossover between the Star Wars and Indiana Jones franchises. The appearance and corresponding location of Jones' homeworld (which is heavily implied but not directly stated to be Earth) implied that it was Mars.
