The Rings 

Like many planets, Uranus has rings of its own. They are not, of course as bright and as wide as Saturn's, but nonetheless, the rings share many of the same characteristics as Saturn's rings. First discovered during a Voyager mission in 1977, these rings are made up of large ice boulders, dust and rock. The sizes of the particles can range from very small to more than ten meters in diameter. Currently, there are eleven known rings with the possibility of many incomplete rings (arcs) around 50 meters (160 eet).

The outermost ring is called the Epsilon ring, which also happens to be the brightest. The ring is gray in color and, like the other rings, has a low reflectivity. Another characteristic of the Epsilon ring is that it has two shepherd satellites named Cordelia and Ophelia.

On a historical note, the Uranian rings were the first set of planetary rings to be discovered after aturn. This indicated that rings were a common characteristic of planets. It was also a surprise to scientists on the existence of Jupiter's rings.
