Star system

A star system, also known as a solar system, planetary system, or simply a system, was a group of celestial bodies, usually planets, orbiting a star. Most stars in the galaxy had their own planetary system. Navigational routes known as runs connected chains of star systems, and these routes through hyperspace were vital for trade and transit between systems, with some of them crossing sector boundaries, which conceptually grouped star systems across swathes of space into named regions. A single system could contain dozens of planets, even more moons, and any number of celestial bodies, while a single sector could contain multiple star systems.

During the crisis that led to the Clone Wars, several hundred systems that belonged to the Galactic Republic seceded and formed the Confederacy of Independent Systems under the leadership of Count Dooku of Serenno, a former Jedi Master.
