(2956) Yeomans Main-belt Asteroid
Discovered on 28 April 1982 by E. Bowell at Anderson Mesa.
Named in honor of Donald K. Yeomans, celestial mechanician at the Jet Propulsion Laboratory and discipline specialist for the astrometric team of the International Halley Watch. Well known for his orbit determinations that take account of the nongravitational forces acting on comets, he has made a detailed study of the motion of Halley's Comet back to the year -1404 and has analyzed the orbits of meteor showers and their relation to the orbits of parent comets.
