Belinda (moon)

Belinda is a closer moon to Uranus, a planet in the solar system. Belinda was found from the images taken by Voyager 2 on 1986,[5] and it was given the designation S/1986 U 5.[6] It is named after the heroine of Alexander Pope's The Rape of the Lock.[5] It is also designated Uranus XIV.[7]

    Belinda belongs to Portia Group of moons, which also includes Bianca, Cressida, Desdemona, Portia, Juliet, Cupid, Rosalind and Perdita.[4] These moons have similar orbits and photometric properties.[4] Other than its orbit,[1] radius of 45 km[2] and geometric albedo of 0.08[4] almost nothing is known about it.

    At the Voyager 2 images Belinda appears as a stretched object, the major axis pointing towards Uranus. The moon is very stretched, with its short axis 0.5 ± 0.1 times the long axis.[2] Its surface is grey in color.[2]
