Coruscant, also known as Imperial Center or the Queen of the Core, was a planet located in the Galactic Core. 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. In controlling Coruscant, these governments controlled most of the galaxy in the process.

“An incandescent organ of life, visibly vibrating with the pulses of billions.”
―Supreme Chancellor Signet Mezzileen

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. However, in practice, Galactic City and its other names were sometimes applied to the Senate District, the central government center and de facto capital of Coruscant.

Coruscant was known to have the tallest buildings in the Galaxy. Coruscanti skyscrapers dwarfed all the original natural features, including mountains, as well as floors of oceans which once covered a large portion of Coruscant’s surface. Areas of Galactic City were broken up into 5,127 levels which were then divided into megablocks, blocks, and subblocks. Coruscant itself was divided into quadrants, which were divided into zones. Below the skyscrapers was Coruscant’s undercity, where sunlight never reached. Artificial lighting illuminated these lower levels and advertisement holograms could be seen everywhere. There were numerous establishments for entertainment, catering to a myriad of alien species. The residents were collectively referred to as Twilighters.

The planet produced trillions of tons of waste every hour. Though almost everything on the planet, from clothes to packaging and machinery was recyclable, some waste was too dangerous to recycle. Such items included worn-out hyperdrive cores which were delivered to one of the planet’s five thousand garbage pits, where they were put into canisters and fired into a tight orbit around the planet. Garbage ships then collected them and transported them to nearby moons for storage. Some of the more dangerous materials were shot into the nearby sun for complete incineration. Garbage not exported or destroyed was mixed into a slurry of silicone oils and processed by garbage worms which chewed it into pellets while removing any remaining organics, plastic, or recoverable metals. They turned millions of tons of pellets into carbon dioxide, methane, and other gases.

Coruscant’s enormous population and industrialization also produced massive amounts of carbon dioxide and heat energy. Thousands of carbon dioxide-reactive atmospheric dampeners were put into place in the upper atmosphere to prevent atmospheric degeneration. The first set of these planet-wide dampeners, developed by the Galactic Republic, was known as the Coruscant Atmospheric Reclamation Project.
