Bianca orbiting Uranus

Bianca is a closer moon to Uranus. It was found from the images taken by Voyager 2 on 1986-01-23, and was given the 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 Portia Group of moons, which also includes Cressida, Desdemona, Juliet, Portia, Rosalind, Cupid, Belinda and Perdita. These moons have similar orbits and photometric properties. Other than its orbit, radius of 27 km and geometric albedo of 0.08 almost nothing is known about it.

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