Corellia was the capital planet of the Corellian system, which included Selonia, Drall, Tralus, and Talus. It was also the birthplace of smuggler and New Republic General Han Solo and Rogue Squadron pilot and New Republic hero Wedge Antilles.
Collectively, the planets of the system were known as the Five Brothers. As the largest planet and the closest to Corell, Corellia was often called the "Eldest Brother" or the "Eldest." Historians believed the Celestials assembled the system artificially, the worlds brought from other parts of the galaxy for unknown reasons. Some believed that these Celestials populated Corellia with Humans from Coruscant.
