Gas giant

A gas giant was a planet that was primarily composed of gaseous or liquid layers. Due to their high mass and sheer size, most gas giants had more than one or even several moons, and some of them possessed large, and beautiful ring systems. Most gas giants were made of hydrogen and helium, the two lightest elements in the Universe, with some methane, but a rare few had oxygen abundant atmospheres, providing a life zone. Famous gas giants included Bespin, Endor, Talloran and Yavin Prime.
