Coruscant
Coruscant is known as the center of the universe and the seat of government since the earliest days of the Republic. The planet's surface is essentially a single, enormous multilevel city with buildings that extend as much as 6,000 meters into the atmosphere. The skies of Coruscant are a constant hive of activity that is crowded with starships from around the galaxy traveling the planet in tightly controlled sky lanes. The Emperor directly controls the Imperial Navy and Galactic Senate from here.[1]
