The Atterra system, a binary star system, resided within the Outer Rim Territories of the galaxy. It encompassed a minimum of three planets: Atterra Alpha, Atterra Bravo, and the gas giant known as Atterra Primo.
Prior to the Destruction of the Hosnian system, the First Order held dominion over this system. In response, the Resistance dispatched multiple bombers, disguised as freighters, to run supplies to Atterra.
