As with Jupiter, ... Astronomers can infer the chemical make up of a planet by knowing its density and comparing it to the known densities of compounds. ... For example, the density of water is 1 g/cm3, and the density of rock is about 3 g/cm3. Since Saturn's density is less than water, it is made up mostly of gases,
