Juliet 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 the 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] Other than its orbit,[3] size of 150 × 74 km[4] and geometric albedo of 0.08,[6] virtually nothing is known about Juliet.
In 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.[4] Its surface is grey in color.[4]
Juliet may collide with Desdemona within the next 100 million years.[9]
