Abstract
Reflection spectra and thermal-emission radiometry were obtained for the Earth-crossing asteroid 1984 KB. The spectrum exhibits the spectral signatures of olivine, pyroxene, and NiFe metal; it is typical of Class S objects and suggests a surface material similar to the rare lodranite meteorites. A standard asteroid thermal model implies a radius of ∼0.7 km and an albedo of ∼0.16 (similar to Class S objects). An analysis of the same thermal data with a bare-rock thermal model gives an albedo inconsistent with the IR spectrum, suggesting that this object has a significant regolith despite its small size.
