9819 Sangerhausen           Discovered 1971 Mar. 25 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
In the vicinity of the German city of Sangerhausen, a remarkable archaeological object was unearthed. This 4000-year-old bronze disc shows a quasi-real starry sky. Its similarity to Homer's Iliad 18, 484--486 is striking. The name was suggested by W. Schlosser and L. D. Schmadel.
