 The "Collaborative Asteroid Lightcurve Link" derives an albedo of 0.0792 and a diameter of 39.29 km based on an absolute magnitude of 10.4.Further published mean-diameters and albedos by the WISE team include () and () with corresponding albedos of () and ().An asteroid occultation on 21 November 2004, gave a best-fit ellipse dimension of 39.0 × 39.0 kilometers.
