surface has an albedo of (), () and (), respectively. The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0560 and calculates a diameter of 62.73 kilometers based on an absolute magnitude of 10.74. Alternative mean-diameter measurements published by the WISE team include in ascending order (), (), () and () and albedos of (), (), () and (). An asteroid occultation, observed on 23 March 2009, gave a best-fit ellipse dimension of 63.0 × 63.0 kilometers. These timed observations are taken when the asteroid passes in front of a distant star.
