2658 Gingerich (1980 CK) is a main-belt asteroid discovered on February 13, 1980 by Harvard College at Agassiz Station. It rotates quickly, with a spin period of 2.9415 hours. Gingerich is also suspected to be a binary asteroid, due to a decrease in the magnitude of its lightcurve observed on Nov. 20, 2005. It is named for Owen Gingerich.
