43224 Tonypensa           Discovered 2000 Jan. 8 by the Lincoln Laboratory Near-Earth Asteroid Research Team at Socorro.
Anthony Pensa (b. 1943) provided leadership and expertise in the space surveillance community since joining MIT Lincoln Laboratory in 1969. As head of the Laboratory's Aerospace Division (1996-2001) he oversaw the initiation of the LINEAR program. This naming is on the occasion of his retirement as assistant director.
