 A large number of near-Earth objects are thought to be contact binaries.The "Collaborative Asteroid Lightcurve Link" assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 1.1 kilometers, while photometric observations by Italian Albino Carbognani at Saint-Barthelemy Observatory () gave a diameter of kilometers.In September 2013, a rotational lightcurve of "Pan" was obtained from photometric observations by American astronomer Brian Warner at his Palmer Divide Station () in Colorado.
