Bianca 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.[9] It was named after the sister of Katherine in Shakespeare's play The Taming of the Shrew. It is also designated Uranus VIII.[10]

There is also an asteroid called 218 Bianca.

Bianca belongs to the 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,[3] size of 64 × 46 km,[4] and geometric albedo of 0.08[6] virtually nothing is known about it.

In 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.[4] Its surface is grey in color.[4]
