Yavin's atmosphere was made up of thick clouds swept about by violent, hurricane-force winds. Of its overall total of 26, Yavin had two other moons that were habitable Yavin 8 and Yavin 13. Yavin was best known for its moon, Yavin 4, which was the location of the Rebel Alliance's base prior its discovery and near destruction in the Battle of Yavin. It was located on the backward Gordian Reach, a hyperspace route from which the sector got its name.
