C-type asteroids

The most common class of asteroid in the outer main belt, having surfaces that are similar in composition to carbonaceous chondrite meteorites. Ultraviolet absorption features vary in relative strength according to the amount of water of hydration in the surface material. There are three subclasses: B-type asteroids have a higher albedo than the average C; F-types have weak to nonexistent UV absorption features; G-types have a strong UV absorption feature.
