Coruscant

Coruscant was a planet located in the Core Worlds. Located at the intersection of numerous major hyperlanes— including the Perlemian Trade Route, the Corellian Run, the Metellos Trade Route, the Koros Trunk Line, and the Leisure Corridor—its hyperspace coordinates were (0,0,0) which effectively made it the center of the galaxy. These coordinates also inspired the planet's military designation, "triple zero," though the actual galactic center was located in the Deep Core. As the de facto center of the galaxy, however, Coruscant was generally agreed to be the most important planet throughout most of galactic history, as well as being one of the wealthiest due to its advantageous location.[19]

Coruscant served as the capital for the Galactic Republic, Galactic Empire, New Republic, Yuuzhan Vong Empire, Galactic Alliance, the Fel Empire, Darth Krayt's Galactic Empire, and the Galactic Federation Triumvirate. It also served at various times as the home of the Jedi Order and the Jedi Temple.
