Saturn is the second-largest planet in the solar system by both volume and mass. It is 95 times the mass of the Earth, and it occupies 760 times the Earth's volume, according to Space.com.
Like Jupiter, the largest planet, Saturn is a gas giant that lacks a solid surface. The planet is made up almost entirely of hydrogen and helium with some trace elements present in small quantities. Space.com reports that Saturn has 53 moons, which is the highest number known for any planet, and rings made predominantly of dirty ice. It is also the second-fastest spinning planet, with Jupiter being the fastest.
