10445 Coster           Discovered 1973 Sept. 29 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
With de Hevesy, Dutch physicist Dirk Coster (1889-1950) discovered the metallic element 72 hafnium, which closely resembles 40 zirconium in that it is resistant to high temperatures. The name was suggested by W. A. Fröger.
