1973 UD. Discovered 1973 Oct. 25 by P. Wild at Zimmerwald.

Named in honor of Joachim Schubart {1928- }, Astronomisches Rechen-Institut, who has developed averaging techniques for studying the long-term motions of minor planets and used them to investigate in detail the theory of the Hilda {see planet (153)} group of minor planets, of which this is a member. With P. Stumpff he has produced a widely-used computer program for the numerical integration of n bodies and has utilized it in determinations of the masses of (1) Ceres and (2) Pallas. (M 3937)
