Starbase 7 is the only starbase in the Andor sector, located at a class K planet which orbits the white dwarf star CJ-884. The base has a planetary outpost as well as space station facilities, which included a free-floating orbital space station, as well as a space station that existed incorporated into the surface of an asteroid. Starbase 7 is the closest starbase to Andoria and is the official headquarters of the Starfleet 7th Fleet. It is also very close to the star systems Ejul Thelni and Alpha Centauri. Starbase 7 serves as a supply base for ships patrolling the Romulan Star Empire' border. (TOS novel: Crisis on Centaurus; Last Unicorn RPG module: The Andorians: Among the Clans)
