- *Uranus' Moon: Ariel
Ariel's surface is a mixture of cratered terrain and systems of interconnected valleys hundreds of kilometers long and more than 10 km deep.

- *Uranus' Moon: Oberon
Oberon's heavily cratered surface has probably been stable since its formation. Some of the craters have rays of ejecta similar to those seen on Callisto. Some of the crater floors are dark, perhaps covered with darker material (dirty water?) that upwelled into the crater.

- *Uranus' Moon: Titania
Titania's surface is a mixture of cratered terrain and systems of interconnected valleys hundreds of kilometers long. Some of the craters appear to be half-submerged.

- *Uranus' Moon: Umbriel
Umbriel is very dark; it reflects only about half as much light as Ariel, Uranus' brightest satellite.

- The Rings of Uranus
The rings were discovered from the Earth in 1977 when Uranus occulted (passed in front of) a star and it was noticed that there were dips in the brightness of the star before and after it passed behind the body of Uranus.

- The Surface and Interior of Uranus
Uranus has a relatively featureless appearance at visible wavelengths. Even from Voyager 2 at a distance of 80,000 km there were few distinguishable features.

- Voyager Mission to Uranus
NASA's Voyager 2 spacecraft flew closely past distant Uranus, the seventh planet from the Sun, in January 1986. At its closest, the spacecraft came within 81,500 kilometers (50,600 miles) of Uranus's cloudtops on Jan. 24, 1986.
