 The "Collaborative Asteroid Lightcurve Link" adopts Petr Pravec's revised WISE-data and takes an albedo of 0.2151 with a diameter of 12.67 kilometers based on an absolute magnitude of 11.773.Several rotational lightcurve of "Gehrels" were obtained from photometric observations by astronomers Wiesław Wiśniewski, Petr Pravec, Pierre Antonini, Raoul Behrend, Donn Starkey, Laurent Bernasconi, Jacques Montier, Serge Heterier, Daniel Klinglesmith and Robert Stephens.Lightcurve analysis gave a rotation period between 2.83 and 2.840 hours with a brightness variation of 0.21 and 0.27 magnitude ().
