Desdemona (moon)
Desdemona is a closer moon to Uranus. It was found from the images taken by Voyager 2 on 1986-01-13, and was given the designation S/1986 U 6.[5] Desdemona is named after the wife of Othello in William Shakespeare's play Othello. It is also designated Uranus X.[6]

Desdemona belongs to Portia Group of moons, which also includes Bianca, Cressida, Juliet, Portia, Rosalind, Cupid, Belinda and Perdita.[4] These moons have similar orbits and photometric properties.[4] Unfortunately, other than its orbit,[1] radius of 34 km[2] and geometric albedo of 0.08[4] almost nothing is known about it.
At the Voyager 2 images Desdemona appears as a stretched object, the major axis pointing towards Uranus. The ratio of axises of the Desdemona's prolate spheroid is 0.6 ± 0.3.[2] Its surface is grey in color.[2]
