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.

    $\begingroup$ 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. $\endgroup$

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.
