(20512) Rothenberg Main-belt Asteroid
Discovered on 10 September 1999 by A. Knofel at Drebach.
Eckehard Rothenberg (b. 1938) is technical director of the Archenhold Observatory in Berlin-Treptow and in the past leader of a youth study group there. Many of the group's former members (including the discoverer) are today active amateur and professional astronomers and owe him for a considerable share of their knowledge.Naming citation (20010309/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
