individual ringlets and all of these rings circle the planet. There are dark spots in some places on the rings and in the past have been mistaken for some of Saturn’s moons and one of the moons is thought to have given particles to one of the rings and they orbit together. The rings are visible from Earth and they start from the top of Saturn’s atmosphere to well beyond the orbits of its closest moons, about a distance of 84,650 miles (136,200 km) from the center of Saturn. The rings are very thin measuring no more than a few kilometers (about a mile) in thickness.

significant atmosphere. It probably consists of equal amounts of rock and water ice and the temperature on the surface is around -182° C (about -296° F). The sixteenth moon of Saturn is Hyperion and was discovered by Bond and Lassell in 1848, it was named after the son of Earth and Uranus. It measures approximately 370 x 280 x 225 km (229 x 174 x 140 mi) and orbits outside of the moon Titan. Because of its odd shape scientist believe that it use to be part of a larger and rounder moon that must have broken apart. It is the largest object in our Solar System that is not ball shaped. Iapetus was discovered by Cassini in 1671 and was named after the son of Uranus. It is believed to consist of all water ice and its surface is still a mystery, being of a dark material one side and white and bright on the other, and only visible from one side of its orbit, it could be explained in two different ways. One way is that the dark material erupted from the interior of Iapetus into a low area of the leading hemisphere, or the second is that this dark material falls from the moon Phoebe, which also has a dark exterior. Iapetus and Phoebe are not only similar in their dark exteriors but they also orbit Saturn they same, from top to bottom. As Iapetus is one of the closest moons to Saturn, Phoebe is the farthest. Phoebe was named for the daughter of Uranus and Earth, and was discovered in 1898 by Pickering. Because of its orbit and dark exterior scientists believe that it is a captured asteroid or comet.
