Ruusan 2, which some also called the Ruusan moon, was just one of three moons that circled Ruusan, a planet found within the Ruusan system of the Teraab sector. This system itself resided in the Mid Rim region of the galaxy, specifically at coordinates P-11 on the Standard Galactic Grid. Skytop Station, a clandestine listening post operated by the Separatist faction, was situated on this moon during the Clone Wars.
