2478 Tokai
2478 Tokai (1981 JC) is a main-belt asteroid discovered on May 4, 1981 by T. Furuta at Tōkai, Aichi.
Since the albedo of this asteroid is unknown, the size can only be estimated as between about 7 km - 15 km,[3] based on the absolute magnitude (H) of 12.8.[1]
Satellite
Photometric observations in 2007 revealed a ~7+km satellite (lower limit diameter ratio of 0.72) with an orbital period of 25.88 hours.[2]
