Desdemona is aninner satellite ofUranus. It was discovered from the images taken byVoyager 2 on 13 January 1986, and was given the temporary designationS/1986 U 6.[12] Desdemona is named after thewife of Othello inWilliam Shakespeare's playOthello. It is also designatedUranus X.[13]

Desdemona belongs to the Portia group of satellites, which also includesBianca,Cressida,Juliet,Portia,Rosalind,Cupid,Belinda, andPerdita.[9] These satellites have similar orbits and photometric properties.[9] Other than its orbit,[5] size of 90 km × 54 km (56 mi × 34 mi),[6] and geometric albedo of 0.08,[9] little is known about Desdemona.

InVoyager 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.[6] Its surface is grey in color.[6]

Desdemona may collide with one of itsneighboring moonsCressida orJuliet within the next 100 million years.[14]
