Saturn's volumetric mean radius is 58,232 km. Remarkably, Saturn is less dense than [[water]]. Its chief constituent is molecular [[hydrogen]], followed by [[helium]], [[methane]], [[ammonia]], [[hydrogen deuteride]], and [[ethane]]. Aerosols of ammonia ice, water ice, and [[ammonia hydrosulfide]] complete Saturn's composition.

Saturn's volumetric mean radius is 58,232 km. Remarkably, due to its composition of various gases, Saturn is less dense than [[water]]; however, a body which could hold a large enough volume of water to enable Saturn to float has not yet been constructed. Its chief constituent is molecular [[hydrogen]], followed by [[helium]], [[methane]], [[ammonia]], [[hydrogen deuteride]], and [[ethane]]. Aerosols of ammonia ice, water ice, and [[ammonia hydrosulfide]] complete Saturn's composition.
