It was discovered on 4 March 1907, by German astronomer August Kopff at the Heidelberg-Königstuhl State Observatory in southwest Germany.
[1] Conversely, the Wide-field Infrared Survey Explorer (WISE) characterized it as a primitive P-type asteroid.
[6] Photometric observations of this asteroid by American astronomer Frederick Pilcher at the Organ Mesa Observatory (G50) in Las Cruces, New Mexico, during May 2012 gave a well-defined lightcurve with a rotation period of 27.888 hours and a brightness variation of 0.35 in magnitude (U=3).
[11] The result supersedes a tentative period of at least 24 hours obtained by French amateur astronomer Pierre Antonini in March 2011 (U=2-).
[5][6][7][8][9] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0786 and a diameter of 48.51 kilometers based on an absolute magnitude of 9.95.
