Moons and Rings
In this amazing image from NASA's Cassini spacecraft, one of Saturn's moons can be seen among the planet's delicate rings. The small moon above the rings is Epimetheus, which is only 72 miles (116 km) in diameter. The large moon behind the rings is Titan, Saturn's largest moon and the second largest moon in the Solar System. Titan is 3,200 miles (5,151 km) in diameter. Its fuzzy atmosphere is composed mainly of nitrogen along with some hydrocarbons such as methane, ethane, and ethane, hydrogen cyanide. These hydrocarbons give Titan its distinctive orange color.
