Saturn

Best known for its rings, made up almost entirely of water ice in fragments ranging from dust grains to house-sized chunks. It's so low in density that, in theory, it would float in an ocean large enough to hold it. Its moon Titan has an atmosphere of its own, and lakes of liquid methane on its surface.
