C-type asteroid

[1] They are volatile-rich and distinguished by a very low albedo because their composition includes a large amount of carbon, in addition to rocks and minerals.

Asteroids of this class have spectra very similar to those of carbonaceous chondrite meteorites (types CI and CM).

The latter are very close in chemical composition to the Sun and the primitive solar nebula minus hydrogen, helium and other volatiles.

The potentially brightest C-type asteroid is 324 Bamberga, but that object's very high eccentricity means it rarely reaches its maximum magnitude.

In the Tholen classification, the C-type is grouped along with three less numerous types into a wider C-group of carbonaceous asteroids which contains:[citation needed] In the SMASS classification, the wider C-group contains the types:[citation needed]
