5109 Robertmiller           Discovered 1987 Sept. 13 by H. Debehogne at the European Southern Observatory.
Robert J. Miller (b. 1950), astronomer at the U.S. Naval Observatory since 1972, worked on the six-inch transit circle programs and became one of the most prolific observers in that telescope's 100-year history. From 1996 until his retirement on 2006 Jan. 2 he worked in the Nautical Almanac Office.
