A giant light enough to float in water, if you could find a bathtub big enough, wearing the most spectacular rings in the solar system.
Saturn is a gas giant made mostly of hydrogen and helium. Its bright rings are made of countless pieces of water ice and rock, from dust grains to boulders; they are hundreds of thousands of kilometres wide but mostly only tens of metres thick.
Its average density, about 0.69 g/cm³, is lower than that of water. Its largest moon, Titan, has a thick atmosphere, and the small moon Enceladus sprays water ice from an underground ocean.
