8250 Cornell           Discovered 1980 Sept. 2 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Named for Cornell University, on the occasion of its hosting the "Asteroids, Comets, Meteors" conference in July 1999. Cornell was founded in Ithaca, New York, in 1865 by Ezra Cornell. An acknowledged center for discovery, academic leadership and service, it is, in a very real sense, a world treasure. The university operates the Arecibo Observatory, the premier site for radar astronomy in the world, and it continues to play a leading role in the exploration of minor planets and comets by spacecraft. Name proposed and citation written by J. Veverka.
