(34420) Peterpau is a major outer belt asteroid discovered on September 23, 2000 by the Canadian astronomer of Hong Kong origin William Kwong Yu Yeung at the Desert Beaver Observatory near Eloy , Arizona ( IAU code 919). Unconfirmed sightings of the asteroid had already occurred in 1998 (1998 HE 62 ) at the Lincoln Laboratory Experimental Test System in Socorro , New Mexico as part of the Lincoln Near Earth Asteroid Research (LINEAR) project.
(34420) Peterpau belongs to the Hygiea family, a rather older group of asteroids, as is suspected, the largest member of which is the asteroid (10) Hygiea . According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic investigation by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (34420) Peterpau assumed a dark surface, so it could, roughly speaking, be around trade a C asteroid .
The timeless (non- osculating ) orbital elements of (34420) Peterpau are almost identical to those of two smaller asteroids, assuming the absolute magnitude of 15.8 and 15.6 compared to 13.6: (209480) 2004 HD 30 and ( 223445) 2003 SF 309 .
(34420) Peterpau was named on February 19, 2006 after the American Oscar winner of Hong Kong origin Peter Pau . Pau is a cameraman .
