The asteroid is estimated to measure between 950 meters and 1.8 kilometers in diameter and was named after German astronomer Erwin Schwab in 2009.
[5]: 23 The asteroid orbits the Sun in the inner main-belt at a distance of 2.0–2.8 AU once every 3 years and 8 months (1,342 days).
[1] The Nysa family complex consist of S-, F- and C-type asteroids (SFC).
[4] Since members of the Nysa family complex also include carbonaceous asteroid, Erwinschwab's albedo may also be estimated at 0.057, which translates into a larger diameter of 1.8 kilometers.
[6] This minor planet was named after German amateur astronomer Erwin Schwab (born 1964), a prolific discoverer of minor planets at the Starkenburg Observatory, Tzec Maun and Taunus observatories since the early 1980s.
