Uranus' Moons and Rings

Uranus has fascinating moons and a complicated ring system. The ring system is a completely different form of ring system than that found at Saturn or Jupiter. At Uranus there is even a very obvious partial ring, or "ring arc".

Many moons are icy moons with fascinating surface features. These icy moons have neither an atmosphere nor a magnetosphere, and there is not much possibility for life. The surfaces of these moons indicate that the interiors of the moons may possibly been active in the past, however.

The moons are, in order; Cordelia, Ophelia, Bianca, Cressida, Desdemona, Juliet, Portia, Rosalind, Belinda, and Puck. These moons are part of a class of moons called the "Small Moons". Icy moons of Uranus are; Miranda, Ariel, Umbriel, Titania, Oberon, Caliban, and Sycorax. In 1999, four more Uranian moons were found. They include Prospero, Setebos, Stephano and 1986 U 10.
