53468 Varros           Discovered 2000 Jan. 2 by S. Sposetti at Gnosca.
George Varros (b. 1959) is an amateur astronomer who helped NASA's Meteoroid Environment Office popularize lunar-meteoroid-impact monitoring by amateur astronomers, for the purpose of assessing the dangers to future astronauts during prolonged visits to the lunar surface.
