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 Voyager 2 imagery, 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]
