Bianca (pronounced /biˈɑːŋkə/ bee-AHNG-kə) is an inner satellite of Uranus. It was discovered from the images taken by Voyager 2 on January 23, 1986, and was given the temporary designation S/1986 U 9.[7] It was named after the sister of Katherine in Shakespeare's play The Taming of the Shrew. Originally, it was to be called Peaseblossom after a fairy in Shakespeare's A Midsummer Night's Dream, but due to a nomenclature conflict between the USA and the USSR the name Bianca was quietly chosen by the IAU a few years after the moon's discovery. It is also designated Uranus VIII.[8]

Bianca belongs to Portia Group of satellites, which also includes Cressida, Desdemona, Juliet, Portia, Rosalind, Cupid, Belinda and Perdita.[6] These satellites have similar orbits and photometric properties.[6] Other than its orbit,[1] radius of 27 km,[2] and geometric albedo of 0.08[6] virtually nothing is known about it.

At the Voyager 2 images Bianca appears as an elongated object, the major axis pointing towards Uranus. The ratio of axes of the Bianca's prolate spheroid is 0.7 ± 0.2.[2] Its surface is grey in color.[2]
