Above a picture of Belinda (Uranus XIV)from Voyager 2 images from which these satellites were discovered.


Note that these satellites always present the same face to Uranus, as most of the satellites close to giant planets.

Values ​​for Cordelia, Ophelia and Puck are repeated here for comparison.
Satellite 1986 U10 (Perdita U-26) was lost, rediscovered in 1999 by Karkoschka on Voyager 2 images, then lost again and finally found by the HST in 2003 (Showalter and Lissauer).
