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. It was named after the sister of Katherine in Shakespeare's play The Taming of the Shrew. It is also designated Uranus VIII.
Bianca belongs to the Portia group of satellites, which also includes Cressida, Desdemona, Juliet, Portia, Rosalind, Cupid, Belinda, and Perdita. These satellites have similar orbits and photometric properties. Other than its orbit, size of 64 × 46 km, and geometric albedo of 0.08, virtually nothing is known about it.
In Voyager 2 images Bianca appears as an elongated object, with its major axis pointing towards Uranus. The ratio of axes of the Bianca's prolate spheroid is . Its surface is grey in color.
