(7133) Kasahara Main-belt Asteroid
Discovered on 15 October 1993 by Endate, K., Watanabe, K. at Kitami.
Named in honor of Shin Kasahara (b. 1953), doctor of dentistry and senior lecturer at Tohoku University. An amateur astronomer, he has been enthusiastically engaged in positional observation and orbit calculation of minor planets and comets since 1973. He also played an important role in designing and constructing the biggest portable telescope in Japan, the 84-cm Chiro Memorial Telescope, which went on a national tour to allow the observation of comet 1P/Halley. Name proposed by the discoverers following a suggestion by M. Koishikawa and A. Fujii.Naming citation (19981005/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
