Climate: Humid Terrain: Jungle Affiliation: Rebel Alliance, Sith Associations: Massassi Temple

A remote world that became a focal point in galactic history, Yavin 4 is a jungle moon orbiting the gas giant of Yavin. Its steamy jungle canopy and abandoned native temples formed the perfect hiding place for an early Alliance base. The native Massassi had long been extinct by the time General Dodonna's Rebel forces erected a hidden fortress on the moon.

When the Empire discovered the location of the Rebels by following a homing beacon secreted aboard the Millennium Falcon, the Death Star soon appeared in the Yavin system. The battle station had to orbit the gas giant Yavin for a clear shot at the smaller moon. The Rebel forces had a scant 30 minutes to launch a counterattack.

Armed with knowledge of the Death Star's sole weakness, Alliance starfighter pilots soared toward the Imperial superweapon. Thus began the Battle of Yavin, which, due to the efforts of Luke Skywalker, became the first major victory of the Rebel Alliance.
