surface has an albedo of (), () and (), respectively. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0656 and a diameter of 51.89 kilometers based on an absolute magnitude of 10.0. Alternative mean-diameter measurements published by the WISE team include (), () and () with corresponding albedos of (), () and (). Several asteroid occultation observed between 2010 and 2014 gave a best-fit ellipse dimension of 52.0 × 52.0 kilometers (one observation) and 63.0 × 63.0 kilometers (three observations). These timed observations are taken when the asteroid passes in front of a distant star.
