D-type asteroid

D-type asteroids have a very low silicates, carbon and anhydrous silicates, possibly with water ice in their interiors. D-type asteroids are found in the outer asteroid belt and beyond; examples are 152 Atala, and 944 Hidalgo as well as the majority of Jupiter trojans. It has been suggested that the Tagish Lake meteorite was a fragment from a D-type asteroid, and that the Martian moon Phobos is closely related.[1]

The Nice model suggests that D-type asteroids may have originated in the Kuiper belt.[2] There are 46 D-type asteroids which include 3552 Don Quixote, 944 Hidalgo, 624 Hektor, and 10199 Chariklo.[3]
