Only Jupiter is larger than Saturn. The rings were first seen by Galileo and are made of ice particles and rock.

    The sixth planet from the Sun, notable for its ring system - first seen by Galileo in 1610, and first explained by Christiaan Huygens in 1656. It has 18 known moons, the largest of which, Titan, has an atmosphere. Its main characteristics are: mass 5.69 × 1026 kg; mean density 0.69 g / cm3; equatorial radius 60 000 km / 37 000 mi; polar radius 53 500 km / 33 300 mi; rotational period (equatorial) 10 h 14 m; orbital period 29.5 years; inclination of equator 27°; mean distance from the Sun 9.54 AU (887 million miles).

    Saturn is a very large gas planet which spins very rapidly on its axis. It spins so fast that it flattens out the top and the bottom of the planet and bulges at its equator. Saturn's atmosphere has winds which can blow at over 1800 kilometers per hour! The white spots on Saturn are believed to be powerful storms.
