13743 Rivkin           Discovered 1998 Sept. 17 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
Andrew S. Rivkin (b. 1969), of the Massachusetts Institute of Technology, has wide-ranging interests, including 3- µ m observations of minor planets, Saturn's rings, stellar dust disks, science education, the moons of Mars and oblique impacts. He has also contributed to NEAR, Deep Space-1, ISO, MUSES-C and Rosetta.
