6625 Nyquist           Discovered 1981 Mar. 2 by S. J. Bus at Siding Spring in the course of the U.K. Schmidt-Caltech Asteroid Survey.
Laurence E. Nyquist (b. 1939) is a planetary scientist at NASA's Johnson Space Center. His meticulous work on the chronometry of a wide range of planetary materials has been pivotal in unraveling the time scales for accretion, differentiation and impacts on meteorite parent bodies.
