Saturn
Saturn is the sixth planet of the Solar System and the second-largest. It is famous for its spectacular system of planetary rings. The planet is a gas giant and has a small solid core of rock and ice. The rest of it is mostly composed of hydrogen and (to a lesser degree) helium.
Saturn is a massive planet, sufficiently large enough to have significant gravitational pull for 62 confirmed moons, 53 of which have names, and 13 of which have diameters larger than 50 kilometers. Some of the named ones are Titan, Mimas, Enceladus, Tethys, Dione, Rhea, Iapetus and Hyperion.
Jemm, Son of Saturn, comes from this planet (Jemm, Son of Saturn #1).
Saturn Girl from the Legion of Super-Heroes and Saturn Queen from the Legion of Super-Villains take their code names from this planet since they are natives of Saturn's largest moon, Titan.
