Discovery image of Ophelia

Ophelia was named after the daughter of Polonius, Ophelia, in William Shakespeare's play Hamlet. It is also designated Uranus VII.

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.
