[1] The first precovery was obtained at El Leoncito in 1969, extending the asteroid's observation arc by 17 years prior to its discovery.
[15] A rotational lightcurves of this asteroid was obtained from photometric observations made by American astronomer Brian Warner at his Palmer Divide Observatory (716) in September 2003.
[11] A second lightcurve from a collaboration of Czech, American and Italian observatories published in November 2013, gave a period of 12.2530 hours (U=n/a).
[6][7][9][8][10] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.08 and a diameter of 25.4 kilometer, slightly below the result obtained by IRAS.
[4] This minor planet was named after American space physicist Geoffrey A. Briggs, director of the Solar System Exploration Division at NASA Headquarters during the 1980s.
