D-type asteroid : ウィキペディア英語版 | D-type asteroid D-type asteroids have a very low albedo and a featureless reddish electromagnetic spectrum. It has been suggested that they have a composition of organic-rich 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.〔() Space.com via Yahoo News, Jan 19, 2014, "Potato-Shaped Mars Moon Phobos May Be a Captured Asteroid"〕 The Nice model suggests that D-type asteroids may have originated in the Kuiper belt.〔William B. McKinnon, 2008, "On The Possibility Of Large KBOs Being Injected Into The Outer Asteroid Belt". ''American Astronomical Society,'' DPS meeting #40, #38.03 ()〕 There are 46 D-type asteroids which include 3552 Don Quixote, 944 Hidalgo, 624 Hektor, and 10199 Chariklo.〔 ==Examples== A list of the first 10 asteroids that are D-type.
