2478 Tokai (1981 JC) is a main-belt asteroid discovered on May 4, 1981 by T. Furuta at T kai, Aichi. Since the albedo of this asteroid is unknown, the size can only be estimated as between about 7 km - 15 km, based on the absolute magnitude (H) of 12.8.Photometric observations in 2007 revealed a ~7+km satellite (lower limit diameter ratio of 0.72) with an orbital period of 25.88 hours. Asteroids (from Greek 'star' and 'like, in form') are a class of Small Solar System Bodies in orbit around the Sun. They have also been called planetoids, especially the larger ones.

Asteroids (from Greek 'star' and 'like, in form') are a class of Small Solar System Bodies in orbit around the Sun. They have also been called planetoids, especially the larger ones. These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disk of a planet and was not observed to have the characteristics of an active comet, but as small objects in the outer Solar System were discovered, their volatile-based surfaces were found to more closely resemble comets, and so were often distinguished from traditional asteroids.
