The Galactic Center Spaceport existed on Coruscant, the planet that served as the galactic capital. The Lost Tribe of Sith gained control of the spaceport in 44 ABY after they had secretly entered the government. During the New Jedi Order's effort to liberate Coruscant from the Sith in that year, the Jedi reached the Galactic Center Spaceport aboard the Plain Lady starliner.
