Saturn
Saturn is the sixth planet from the Sun in the solar system. It is named after the Roman god of the same name, who was Jupiter's father. It also happens to be the gateway. Countless chunks of ice form Saturn's extensive ring system, distinguishable from the other planets. Saturn itself is mostly made of hydrogen and helium and has the lowest average density of any planet, so low that if there was a large tub with a diameter the same as Saturn's, it would float on it. That's just basic science, folks!
