Juliet (pronounced /ˈdʒuːliət/ JEW-lee-ət, or /ˌdʒuːliˈɛt/ JEW-lee-ET) is an inner satellite of Uranus. It was discovered from the images taken by Voyager 2 on 3 January 1986, and was given the temporary designation S/1986 U 2.[7] It is named after the heroine of William Shakespeare's play Romeo and Juliet. It is also designated Uranus XI.[8]

Juliet belongs to Portia Group of satellites, which also includes Bianca, Cressida, Desdemona, Portia, Rosalind, Cupid, Belinda and Perdita.[6] These satellites have similar orbits and photometric properties.[6] Unfortunately, other than its orbit,[1] radius of 53 km[2] and geometric albedo of 0.08[6] virtually nothing is known about Juliet.

At the Voyager 2 images Juliet appears as an elongated object, the major axis pointing towards Uranus. The ratio of axes of Juliet's prolate spheroid is 0.5 ± 0.3, which is rather an extreme value.[2] Its surface is grey in color.[2]

Juliet may collide with Desdemona within the next 100 million years.[9]
