Coruscant is an ecumenopolis planet in the fictional Star Wars universe. It first appeared onscreen in the 1997 Special Edition of Return of the Jedi, but was first depicted and mentioned by name in Timothy Zahn‘s 1991 novel Heir to the Empire. Coruscant is a prominent location in both canon and Legends media that has been produced. Within the narrative of the films, Coruscant-based locations such as the Jedi Temple and Jedi Archives act as the home for the Jedi and in plot terms are frequently used for exposition or to drive other elements of the plot.

Coruscant was historically referred to as Notron or Queen of the Core; 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,^[b] partially destroyed in 27 and 44 ABY); under the Galactic Empire this was Imperial City, 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.

Coruscant lies within the Coruscant Subsector of the Corusca Sector, located in the Core Worlds galactic quadrant region. Coruscant is the sixth planet out of 11 planets in the Coruscant System: Revisse (Venus type), Platoril (Mercury type), Vandor-1 (Mercury type), Vandor-2 (Mercury type), Vandor-3 (Earth type), Coruscant (Trantor type), Muscave (Jupiter type), Stentat (Jupiter type), Improcco (Pluto type), Nabatu (Eris type) and Ulabos (Pluto type). Coruscant has four moons; Centax-1, Centax-2, Centax-3, and Hesperidium. Beyond the system’s planets was the OboRin Comet Cluster (Oort Cloud type), and in between Improcco and Nabatu was an asteroid belt (The Covey). The sun was called Coruscant Prime, which the Star Wars galaxy places as XYZ coordinates 0-0-0 (i.e. the «pole»; instead of the Galactic Center) and the Standard Galactic Grid coordinates were L-9 for all in-universe hyperspace navigation, mapping systems, and astronomical observations.

Coruscant serves as the nexus of socio-economic, cultural, intellectual, political, military, and foreign policies activity within the Star Wars galaxy; at various times, it is the central administrative capital of these governing bodies: the Republic, the Galactic Empire, the New Republic, the Yuuzhan Vong Empire, the Galactic Federation of Free Alliances (Galactic Alliance), the Fel Empire, Darth Krayt’s Galactic Empire, and the Galactic Federation Triumvate. The planet’s strategic position relative to the galactic center, a population of approximately 2 trillion sentients, and control over the galaxy’s main trade routes and hyperspace lanes — Perlemian Trade Route, Hydian Way, Corellian Run and Corellian Trade Spine — that must converge and pass through Coruscant space, cemented its status as the richest and most influential habitable world in the Star Wars galaxy.
