Carbonaceous type asteroid

Stony carbon-rich and volatile-rich meteorite or asteroid, some of the earliest-formed matter in a solar system, and a popular resource for asteroid miners.

Rich in carbon, these bodies are largely pristine and unchanged objects, relics from the formation of their solar system. Rich in organic compounds, they are fairly reddish in coloration, and may contain sizable reservoirs of volatiles such as water ice. They are typically found in the outer most regions of their inner system region, although gravitational scattering over time can of course produce some highly eccentric orbits.
