    It is classified as a rare E-type asteroid and is fairly faint for an object of its type. The overall diameter is estimated to be 23 km and it has a geometric albedo of 0.52.[3] Photometric observations show a rotation period of 6.835 ± 0.001 hours with a brightness variation of 0.20 in magnitude. Using a tri-axial ellipsoidal model derived from light curve data, the overall shape of the asteroid is estimated to be a/b = 1.24 ± 0.12 and b/c = 1.83 ± 0.10, where a/b/c are the three axes of an ellipsoid.[4]
