Cordelia is the innermost known moon of Uranus. It was discovered from the images taken by Voyager 2 on January 20, 1986, and was given the temporary designation S/1986 U 7.[1] It was not detected again until the Hubble Space Telescope observed it in 1997.[7][9] Cordelia takes its name from the youngest daughter of Lear in William Shakespeare's King Lear. It is also designated Uranus VI.[10]
Other than its orbit,[4] size of 50 × 36 km,[5] and geometric albedo of 0.06,[7] virtually nothing is known about it. In the Voyager 2 images, Cordelia appears as an elongated object with its major axis pointing towards Uranus. The ratio of axes of Cordelia's prolate spheroid is 0.7±0.2.[5]
Cordelia acts as the inner shepherd satellite for Uranus's ε ring.[11] Cordelia's orbit is within Uranus's synchronous orbit radius, and is therefore slowly decaying due to tidal deceleration.[5]
Cordelia is very close to a 5:3 orbital resonance with Rosalind.[12]
