Saturn has 145 known moons orbiting the planet. The largest moon is Titan. Titan is larger in volume than the planet [[Mercury]]. Titan is the second-largest moon in the [[Solar System]]. The largest moon is a moon of [[Jupiter]], Ganymede. There are also many rings around Saturn. These rings are made of ice with some rocks and dust. Some people think that that the rings were made by a moon impact or other event. Saturn is about 1,433,000,000 km (870,000,000 mi) on average from the [[Sun]]. Saturn takes 29.6 Earth years to move around the [[Sun]].
