Coruscant

Coruscant (ˈkɒrəsɑːnt) is an ecumenopolis planet in the fictional Star Wars universe. It was first depicted in Timothy Zahn's 1991 novel Heir to the Empire, and made its first on-screen appearance in a scene added to Return of the Jedi for its 1997 re-release. It has gone on to become an important location in the setting and appears frequently in Star Wars media. In-universe, Coruscant is a politically and strategically important planet, serving as the capital and seat of government for the Republic and Empire, as well as the headquarters of the Jedi Order. It is typically depicted as a bustling yet highly stratified planet-spanning metropolis. Throughout the city's development that took place over many centuries, new city blocks were built on top of old ones, forming levels. Coruscant has 5127 levels, with 5127 being the wealthiest and 1 being the poorest. Coruscant has four moons and is the sixth planet out of 11 planets in the system of the same name. It lies within the Coruscant Subsector of the Corusca Sector, located in the Core Worlds galactic quadrant region. The sun, Coruscant Prime, is the zero coordinate of the Star Wars galaxy (as opposed to its galactic center). In Legends, Coruscant was once referred to as Notron or Queen of the Core. It was renamed Imperial Center during the reign of the Galactic Empire (as depicted in the original films) and Yuuzhan'tar during the Yuuzhan Vong invasion (as depicted in the New Jedi Order novel series). The planet's capital city was initially Galactic City (built at least in 100,000 BBY, partially destroyed in 27 and 44 ABY). It was Imperial City under the Galactic Empire and was Republic City (or the City of Spires) under the Galactic Republic. The planet was code-named Triple Zero during the Clone Wars. The demonym and adjective form of the planet name is Coruscanti. In universe, the planet derives its name from a rare and valuable gemstone, the corusca gem (a fictional gem in Star Wars). The lights of the planet-wide city, seen from space, were said to resemble the glittering of the gems.
