7355 Bottke           Discovered 1995 Apr. 25 by Spacewatch at Kitt Peak.
Named in honor of William F. Bottke, Jr., known for his research on the collisional and dynamical evolution of minor planets. He has also contributed to the study of the origin and evolution of NEAs, in particular by analyzing the formation of doublet craters found on the terrestrial planets.
