218 Bianca is a sizeable Main belt asteroid. It is an S-type asteroid.

It was discovered by Johann Palisa on September 4, 1880, in Pola and was named after the Austro-Hungarian opera singer Bianca Bianchi (real name Bertha Schwarz). The Vienna newspapers contained several published accounts of the circumstances surrounding the honor extended to the diva in Spring 1882.[1]

In the late 1990s, a network of astronomers worldwide gathered lightcurve data that was ultimately used to derive the spin states and shape models of ten new asteroids, including (218) Bianca.[2][3]
