Ophelia is a closer moon of Uranus. It was found from the images taken by Voyager 2 on January 20, 1986, and was given the designation S/1986 U 8. It was not seen until the Hubble Space Telescope saw it in 2003.
Unfortunately, other than its orbit, radius of 23 km and geometric albedo of 0.08, almost nothing is known about it. At the Voyager 2 images Ophelia appears as a streched object, the major axis pointing towards Uranus.
