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. It was named Peaseblossom by its discoverers after a fairy in Shakespeare's A Midsummer Night's Dream, however 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.[1] 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] Unfortunately, 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 axises of the Bianca's prolate spheroid is 0.7 ± 0.2.[2] Its surface is grey in color.[2]
