Rosalind 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.[9] 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.[10]

Rosalind belongs to Portia group of satellites, which also includes Bianca, Cressida, Desdemona, Portia, Juliet, Cupid, Belinda and Perdita.[8] These satellites have similar orbits and photometric properties.[8] Other than its orbit,[3] radius of 36 km[4] and geometric albedo of 0.08[8] virtually nothing is known about Rosalind.

In the Voyager 2 images Rosalind appears as an almost spherical object. The ratio of axes of Rosalind's prolate spheroid is 0.8–1.0.[4] Its surface is grey in color.[4]

Rosalind is very close to a 3:5 orbital resonance with Cordelia.[11]
