The Sooma system, situated in the Thanium sector of the Outer Rim Territories within the galaxy, was a star system that housed the planet Sooma. This planet served as the homeworld for the sentient Sooman species.
The Star Wars: Droids comic series, specifically the fourth issue, Droids (1986) 4, initially featured the Sooma system, though without naming it. This issue was released on October 1, 1986 by Star Comics, a Marvel Comics imprint. The system's official identification came later in The Essential Atlas, a reference work authored by Jason Fry and Daniel Wallace and published on August 18, 2009, where it was located in grid square R-6.
