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.[10] It was named after the sister of Katherina in Shakespeare's play The Taming of the Shrew. It is also designated Uranus VIII.[11]
Bianca belongs to the Portia group of satellites, which also includes Cressida, Desdemona, Juliet, Portia, Rosalind, Cupid, Belinda, and Perdita.[7] These satellites have similar orbits and photometric properties.[7] Other than its orbit,[3] size of Template:Cvt,[4] and geometric albedo of 0.08,[7] little 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 Bianca's prolate spheroid is 0.7±0.2.[4] Its surface is grey in color.[4]
