(1643) Brown

Reference work entry

1951 RQ. Discovered 1951 Sept. 4 by K. Reinmuth at Heidelberg.

Named in memory of Ernest William Brown (1866–1938), the Cambridge-Yale mathematical astronomer who spent much of the last fifty years of his life working on the theory of the motion of the Moon, developing the method of G. W. Hill {see planet  (1642)} with spectacular success. He also concerned himself with the problem of the Earth’s variable rotation, studied the motions of minor planets on resonant orbits (particularly the Trojans) and wrote treatises on lunar theory and planetary theory.
