Talk:D-type asteroid

Comment
From the page for P-type asteroids:

"P-type asteroids have 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 interior. P-type asteroids are found in the outer asteroid belt and beyond."

This is the same language, word for word as the description of D-type asteroids. It appears that someone has made a mistake here.

Also, Bill Arnett's "Asteroids" page lists three types of asteroids but does not include either the D or P type. It also mentions that there's more than one classification system. This article needs to address these questions.

This site from Washington State University mentions D-type along with P-type. D-type is generally farther from the Sun and more reddish. Harald Khan (talk) 16:00, 20 November 2007 (UTC)
