The asteroid itself may not be spectacular, but the family of asteroids named after it is one of the most important. One member of the family, 243 Ida, has been visited by spacecraft, and gives some idea how the other asteroids in the family may look.
Based on a model constructed from the lightcurve, the shape of Koronis resembles that of Ida, although it is a bit larger. [1] (http://www.astro.helsinki.fi/~kaselain/asteroids.html)

They include the Hungaria group, Flora family, Nysa-Polana family, Phocaea group, Koronis family, Eos family, Themis family, Cybele group, Alinda group, and Hilda group.
The three largest families (Eos, Koronis, and Themis) have been determined to be compositionally homogeneous.
If the asteroids belonging to them are considered to be fragments of a single parent body, then these parent bodies probably had diameters of 100 to 300 km.
