Rosalind (/[invalid input: 'icon']ˈrɒzəl[invalid input: 'ɨ']nd/ ROZ-ə-lind) 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 4.[6] 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.[7]
Rosalind belongs to Portia group of satellites, which also includes Bianca, Cressida, Desdemona, Portia, Juliet, Cupid, Belinda and Perdita.[5] These satellites have similar orbits and photometric properties.[5] Other than its orbit,[1] radius of 36 km[2] and geometric albedo of 0.08[5] virtually nothing is known about Rosalind.
Rosalind is very close to a 3:5 orbital resonance with Cordelia.[8]
At the Voyager 2 images Rosalind appears as an almost spherical object. The ratio of axes of the Rosalind's prolate spheroid is 1.0-0.8.[2] Its surface is grey in color.[2]
