Cordelia (moon)
Cordelia is the closest moon to Uranus. It was found from the images taken by Voyager 2 on January 20, 1986, and was given the designation S/1986 U 7. It was not seen again until the Hubble Space Telescope observed it in 1997. Cordelia takes its name from the youngest daughter of Lear in William Shakespeare's King Lear. It is also designated Uranus VI. This moon is 148 kilometres (92 mi) wide and is the same size of Mars' smallest moon called Deimos.
