What kind of object is 656 Beagle (1908BU)?

I know it's a minor planet, but that includes a large array of different stuff. Specifically, I am looking at the general chemistry/geology of the object.

This is really an astronomy question, not a physics question. –  David Z May 3 '11 at 21:48

I nominate for reopening based on astronomy being on-topic now. (And besides, astronomy has been physics since before physics was physics by several millennia ;) But if people think it is still too localized, then don't bother reopening. –  Chris White Jun 17 '13 at 4:59
    
@ChrisWhite: Could be too localized, but meh. Reopened. –  Manishearth Jun 17 '13 at 8:19

656 Beagle is a small (~53 km diameter) asteroid with a 3.15 AU semimajor axis. It's luminosity is very faint, with H = 9.92. Nothing seems to be known about its geologic basis, but it certainly does not possess a measurable atmosphere. See http://occsec.wellington.net.nz/planet/2008/updates/080912_656_19331_u.htm for more information.
