Kashyyyk (occasionally spelled Kashyk) is a jungle planet and the home of the Wookiee race and Chewbacca. It is a planet of the Republic but the Confederacy of Independent Systems launched an attack on the planet. The Republic sent Grand Master and Jedi General Yoda and Commander Gree with the 41st Elite Corps to liberate the planet. After Order 66 was executed, the clone troopers then turned on Yoda but he managed to escape and after the transformation of the Galactic Republic into the Galactic Empire, it became an Imperial planet.
After the fall of the Empire, Kashyyyk became a New Republic planet.
Kashyyyk is a temperate jungle planet orbiting around a single star located in the Mid Rim. The planet had a complement of three moons, one of which was orange. The center of the planet was covered with a tropical ocean belt, which contained a number of islands and large coral reefs.
Covered in trees, Kashyyyk served as homeworld to the Wookiee species, while the planet shared a star system with a planet inhabited by the Trandoshan species who were the Wookies' deadly enemies.
