(2128) Wetherill

Reference work entry

1973 SB. Discovered 1973 Sept. 26 by E. F. Helin at Palomar.

Named in honor of George W. Wetherill {1925– }, director of the Department of Terrestrial Magnetism, Carnegie Institution of Washington. Noted for his work on isotopic age determination, meteorites, and the origin of the terrestrial planets, he has been a leading student of the dynamical evolution of orbits of meteorites and planet-crossing asteroids. (2128) is a Mars crosser that lies close to a secular resonance shown by Wetherill to be of importance in the delivery of meteorites and asteroids into Earth-crossing orbits. (M 4787)
