9612 Belgorod           Discovered 1992 Sept. 4 by L. V. Zhuravleva at the Crimean Astrophysical Observatory.
An industrial, scientific and cultural center in southern Russia, close to the Ukrainian border, Belgorod was mentioned in a chronicle in 1237. A fortress established in 1593 made Belgorod a key stronghold in protecting Russia's southern border against the Tatars in the seventeenth century.
