It was discovered on 21 September 1928, by Russian astronomer Grigory Neujmin at Simeiz Observatory on the Crimean peninsula.
[13] In November 2011, the so-far best rated rotational lightcurve of was obtained by American astronomer Robert Stephens at the Center for Solar System Studies in California.
Lightcurve analysis gave a rotation period of 52.92 hours with a brightness variation of 0.38 magnitude (U=3-),[11] superseding observations by Wiesław Z. Wiśniewski and a group of French, Italian and Swiss astronomers, that gave a shorter period of 20 and 24 hours, respectively (U=2/2).
[4][5][6][8] The Collaborative Asteroid Lightcurve Link adopts Petr Pravec's revised WISE data, that is, an albedo of 0.2797 and a diameter of 12.084 kilometers with an absolute magnitude of 11.59.
[3][7] This minor planet was named by the discoverer after Harlow Shapley (1885–1972), American astronomer and director of Harvard Observatory in Cambridge, Massachusetts.
