65357 Antoniucci           Discovered 2002 July 12 by the Campo Imperatore Near Earth Object Survey.
Simone Antoniucci (b. 1977) obtained his degree in physics at "La Sapienza" University of Rome in 2003, with a thesis on infrared spectroscopy of protostars. He is currently a Ph.D. student in Astronomy at Tor Vergata University, Rome, studying Young Stellar Objects using infrared high resolution spectroscopy and interferometry.
