Tarsas III was the third planet of its star system in Sector 001 of the Alpha Quadrant. The planet was orbited by a Luna-like moon and Starbase 74, a Federation Spacedock-type starbase. (TNG: "11001001"; TNG: "Conspiracy", okudagram)
In 2364, the USS Enterprise-D docked at the starbase to undergo routine maintenance check and certain upgrades to its computer systems, performed by a team of Bynars. (TNG: "11001001")
Later that year, the location of Starbase 74 was labeled on the map Starbase Ops Status Sol Sector. (TNG: "Conspiracy", okudagram)
