- There is also a minor planet called 666 Desdemona.
Desdemona 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.[11] Desdemona is named after the wife of Othello in William Shakespeare's play Othello. It is also designated Uranus X.[12]

Desdemona belongs to Portia Group of satellites, which also includes Bianca, Cressida, Juliet, Portia, Rosalind, Cupid, Belinda and Perdita.[8] These satellites have similar orbits and photometric properties.[8] Other than its orbit,[5] size of 90 × 54 km[6] and geometric albedo of 0.08[8] virtually nothing is known about Desdemona.
In 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.[6] Its surface is grey in color.[6]
Desdemona may collide with one of its neighboring moons Cressida or Juliet within the next 100 million years.[13]
