The presence of very low-albedo material on the surfaces of some classes of asteroids (C,P,D) and most comets appears to be related to macromolecular carbon compounds on these bodies. Preliminary detections of an organic spectral signature have been reported for some asteroids. The complex refractory organics that occur in some meteorites are probably the material that makes low-albedo asteroids dark. Comet surfaces and ejected dust particles are also very low albedo, apparently resulting from the radiation processing of organic ices.
