It was first identified as 1951 JS at McDonald Observatory in 1951. The asteroid's first used observation was a precovery taken at Mitaka Observatory (388) in 1955, extending the body's observation arc by 23 years prior to its official discovery observation at Nauchnyj.
In March 2014, a rotational lightcurve was obtained from photometric observations at the U.S. Burleith Observatory in Washington D.C.. It gave a well-defined rotation period of 11.1 hours with a brightness variation of 0.25 magnitude (U=3-)
A previous fragmentary lightcurve obtained by French amateur astronomer Laurent Bernasconi in May 2006, gave a much shorter period of 6.6 hours with an amplitude of 0.06 (U=1).
Diameter and albedo
According to the survey carried out by the Infrared Astronomical Satellite IRAS and the Japanese Akari satellite, the asteroid measures 16.6 and 18.1 kilometers in diameter and its surface has an albedo of 0.06 and 0.07, respectively. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.09 and a diameter of 16.7 kilometers with an absolute magnitude of 12.1
