Coruscant

Coruscant (pronounced /'kɔɹəsɑnt/), originally called Notron, also known as Imperial Center or the Queen   of the Core, is a planet located in the Star Wars Galaxy. It was generally agreed that Coruscant was, during most of galactic history, the most politically important world in the galaxy. At various times, it was the capital of the Galactic Republic, the Galactic Empire, the New Republic, the Yuuzhan Vong empire, the Galactic Alliance, very briefly the Fel Empire, Darth Krayt's Galactic Empire, and theGalactic Federation Triumvirate. In controlling Coruscant, these governments controlled most of the galaxy in the process.

Over the centuries, Coruscant had developed into an ecumenopolis, with a total of 5,127 levels of city built up from the crust by the time of the Clone Wars. The actual planet-wide metropolis of Coruscant was called Galactic City. Under the Galactic Republic, the names Republic City or the City of Spires were also used to reference the city. It was also called Imperial City under the Galactic Empire, and New Republic City under the New Republic. However, in practice, Galactic City and its other names were sometimes applied to the Senate District, the central government center and de factocapital of Coruscant. Under the Yuuzhan Vong, the city and planet were both referred to as Yuuzhan'tar.

Overview
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 actualgalactic 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.[1]

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
