(7766) Jododaira Main-belt Asteroid
Discovered on 23 January 1991 by Endate, K., Watanabe, K. at Kitami.
Named for the place where the first really big star parties were held in Japan, the “Chiro's Star Festivals”, from 1975 to 1984. Jododaira (1600 m above the sea) is near the top of Mt. Azuma, a famous volcano in Fukushima Prefecture in northeastern Japan. After the violent eruption of the volcano in 1893, Percival Lowell climbed the mountain to investigate the result of the eruption. One hundred years later, an astronomical observatory was established there and is open to the public. Name proposed by the discoverers following a suggestion by M. Koishikawa and T. Sato.Naming citation (19981005/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
