2nd of the 4 gas giants. Saturn has at least 20 moons and a prominant ring system. Spins quickly like all the other 4 gas giants. And this produces bands of hazy, yellow clouds that circulate parallel to the equator. Although Saturn is nearly as wide as as Jupiter, it has less than one third of the mass. It is the only planet less dense than water.
