This asteroid is classified as an M-type asteroid and is considered anhydrous but oxidized. Further analysis of the spectra suggests the "presence of either an olivine or high-Ca pyroxene phase
in addition to orthopyroxene ± Type B clinopyroxene". Analysis of light curves based on photometric data show a rotation period of with a brightness variation of in magnitude.
