Rosalind (pronounced /ˈrɒzəlɨnd/ ROZ-ə-lind) is an inner satellite of Uranus. It was discovered from the images taken by Voyager 2 on 1986-01-13, and was given the temporary designation S/1986 U 4.[7] It was named after the daughter of the banished Duke in William Shakespeare's play As You Like It. It is also designated Uranus XIII.[8]
Rosalind belongs to Portia Group of satellites, which also includes Bianca, Cressida, Desdemona, Portia, Juliet, Cupid, Belinda and Perdita.[6] These satellites have similar orbits and photometric properties.[6] Unfortunately, other than its orbit,[1] radius of 36 km[2] and geometric albedo of 0.08[6] virtually nothing is known about it.
At the Voyager 2 images Rosalind appears as an almost spherical object. The ratio of axises of the Rosalind's prolate spheroid is 1.0-0.8.[2] Its surface is grey in color.[2]
