Desdemona (/ˌdɛzd[invalid input: 'ɨ']ˈmoʊnə/ DEZ-di-MOH-nə) is an inner satellite of Uranus. It was discovered from the images taken by Voyager 2 on 13 January 1986, and was given the temporary designation S/1986 U 6.[6] Desdemona is named after the wife of Othello in William Shakespeare's play Othello. It is also designated Uranus X.[7]

Desdemona belongs to Portia Group of satellites, which also includes Bianca, Cressida, Juliet, Portia, Rosalind, Cupid, Belinda and Perdita.[5] These satellites have similar orbits and photometric properties.[5] Other than its orbit,[1] radius of 32 km[2] and geometric albedo of 0.08[5] virtually nothing is known about Desdemona.

At the Voyager 2 images Desdemona appears as an elongated object, the major axis pointing towards Uranus. The ratio of axes of Desdemona's prolate spheroid is 0.6 ± 0.3.[2] Its surface is grey in color.[2]

Desdemona may collide with one of its neighboring moons Cressida or Juliet within the next 100 million years.[8]
