'''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&nbsp;U&nbsp;6'''.<ref name="IAUC 4164" /> Desdemona is named after the [[Desdemona|wife of Othello]] in [[William Shakespeare]]'s play ''[[Othello]]''. It is also designated '''Uranus&nbsp;X'''.<ref name="Gazetteer" />

Desdemona belongs to Portia Group of satellites, which also includes [[Bianca (moon)|Bianca]], [[Cressida (moon)|Cressida]], [[Juliet (moon)|Juliet]], [[Portia (moon)|Portia]], [[Rosalind (moon)|Rosalind]], [[Cupid (moon)|Cupid]], [[Belinda (moon)|Belinda]], and [[Perdita (moon)|Perdita]].<ref name="Karkoschka, Hubble 2001" /> These satellites have similar orbits and photometric properties.<ref name="Karkoschka, Hubble 2001" /> Other than its orbit,<ref name="Jacobson 1998" /> size of 90 × 54 km,<ref name="Karkoschka, Voyager 2001" /> and geometric albedo of 0.08,<ref name="Karkoschka, Hubble 2001" /> virtually nothing is known about Desdemona.

In ''[[Voyager 2]]'' imagery, Desdemona appears as an elongated object, with its major axis pointing towards Uranus. The ratio of axes of Desdemona's prolate spheroid is 0.6 ± 0.3.<ref name="Karkoschka, Voyager 2001" /> Its surface is grey in color.<ref name="Karkoschka, Voyager 2001" />

Desdemona may collide with one of its [[Moons of Uranus#Inner moons|neighboring moons]] [[Cressida (moon)|Cressida]] or [[Juliet (moon)|Juliet]] within the next 100 million years.<ref name="Duncan Lissauer 1997" />
