Descripción
(596) Scheila is a large primitive asteroid observed with a comet-like
apearence last December. We present near-infrared spectra (0.8-2.4
μm) obtained at different rotational phases, covering a whole
rotation period of the object after the ejection event, a spectrum in
the 2.2-4.0 μm region obtained in 2007, and mid-infrared photometry
measured by WISE in Feb. 2010. We show that the surface is homogeneous,
and corresponds to a dark (diameterD=113.3km, albedo at 3.4μm
p3.4=0.068) primitive D-type asteroid. We also find that the best
meteorite analogs are carbonaceous chondrites, in particular those of
the CM sub-group.
