On the same night, it was independently discovered by Soviet astronomer Grigory Neujmin at the Simeiz Observatory on the Crimean peninsula. One week later, on 6 September 1932, it was again independently discovered by German astronomer Karl Reinmuth at Heidelberg Observatory. The Minor Planet Center only recognizes the first discoverer.Orbit and classification

Its orbit has an eccentricity of 0.17 and an inclination of 2° with respect to the ecliptic.The asteroid was first observed as at Heidelberg Observatory in November 1905. The body's observation arc begins as at Johannesburg Observatory in May 1931, or 15 months prior to its official discovery observation at Uccle.
