(3692) Rickman Main-belt Asteroid

Discovered on 25 April 1982 by E. Bowell at Anderson Mesa.

Named in honor of Hans Rickman, a planetary astronomer at Uppsala Observatory and a member of the research group studying minor planets and comets. Rickman is widely known for his theoretical modeling of cometary nuclei, and he is also interested in the relationships between comets and planet-crossing asteroids. He has for a long time favored the popularization of astronomy, and to this end he has written a large number of articles in popular magazines and has lectured to general audiences. Rickman is a co-organizer of the “Asteroids, Comets, Meteors” meetings that are held regularly in Uppsala. Citation prepared by C.-I. Lagerkvist at the request of the discoverer.Naming citation (WGSBN Bull. 4, #10, 4), IAU / Minor Planet Center, via NASA/JPL
