Average distance from the Sun     1,429,400,000 km / 9.54 AU
Diameter     120,536 km (equatorial)
Mass     5.68e26 kg
Orbital period around the Sun     29.46 Earth years / 10,750 Earth days
Number of moons     53 named satellites, 9 recently discovered but not named
Ring System     about 7 distinct rings, about 250,000 km or more in diameter
Saturn’s most distinctive feature is the thousands of rings that orbit the planet. Saturn’s rings are beautiful even in small amateur telescopes, especially when the planet is at its greatest tilt to the Earth, exposing the maximum surface area of the ring system. The ring particles seem to be composed primarily of water ice, but they may also include rocky particles with icy coatings. Saturn has more than 30 moons. The largest, Titan, is prominent in views through a small telescope. Saturn is less dense than water—if you could fit Saturn in a bathtub, it would float.
