7011 Worley           Discovered 1987 Sept. 21 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Named in memory of Charles Edmund Worley (1935-1997), indefatigable observer and cataloguer of double-star positions. Following two years at the Lick Observatory, he was on the staff of the U.S. Naval Observatory from 1961. His work has significantly enhanced our knowledge of the motion of double-star and multiple-star systems and of stellar masses. Name suggested by H. Eichhorn.
