The Galactic Center of Coruscant (pronounced /’kʊɹəsɑnt/), also known as Imperial Center or the Queen of the Core, has been the political hub of the galaxy for millennia. It is generally agreed that Coruscant has been, during most of Galactic history, the most politically important world in the galaxy. It was the capital of the Galactic Republic, and is currently the capital of the Galactic Empire.
A large number of the galaxy’s trade routes—including the Perlemian Trade Route, the Corellian Run, the Metellos Trade Route, the Koros Trunk Line, and the Leisure Corridor through Coruscant, making it one of the richest worlds in the galaxy. Tellingly, the planet’s hyperspace coordinates are (0,0,0), and the military designation is Triple Zero. Accordingly, it is the main planet of the all-important ‘Sector Zero’, a military designation for the Coruscant and surrounding systems.
Geologically, the planet is composed of a molten core with a rocky mantle and a silicate rock crust. At its poles are huge ice caps that are popular spots for tourists. The entire surface of Coruscant is covered by sprawling kilometers-high skyscrapers and cities, and boasts a population of over a hundred billion to several trillion, depending on the era. Following the end of the Clone Wars, an official census noted 1 trillion official permanent residents. The statistics did not include transients, temporary workers, unregistered populace nor residents of orbital facilities. Because of these omissions, the “real” population of Coruscant is estimated to be three times the official amount.
Coruscant is currently officially known as Imperial Center. The Imperial Palace is located planet-side and a large portion of the Imperial administration is based there as well. Because of the humanocentric policy of the Empire, non-humans are segregated in to large ethnic neighborhoods, the largest of which is known as Invisec.
