10254 Hunsrück           Discovered 1973 Sept. 29 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
The Hunsrück lies west of the Rhine between the rivers Nahe and Mosel. In the southern part many semiprecious stones are found, helping create a jewelry industry.
