WebMay 5, 2024 · C-type asteroids make up more than 75 percent of known asteroids. The "C" stands for carbon, and the surfaces of these extremely dark asteroids are almost coal-black. C-type asteroids are the most common variety, forming around 75% of known asteroids. 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. They have an average density of about 1.7 g/cm . They lie most … See more Asteroids of this class have spectra very similar to those of carbonaceous chondrite meteorites (types CI and CM).
