It was discovered by German astronomer August Kopff at Heidelberg Observatory on 12 September 1906.〔 The S-type asteroid is a member of the Eos family. It orbits the Sun at a distance of 2.9–3.2 AU once every 5 years and 3 months (1,913 days). Its orbit shows an eccentricity of 0.05 and is tilted by 9 degrees to the plane of the ecliptic. It has a long rotation period of 18 hours〔 and an albedo of about 0.12, according to the surveys carried out by IRAS, Akari, WISE and NEOWISE.〔〔〔〔 The asteroid was named by the Minor Planet Center in honor of German Catholic priest and amateur astronomer Otto Kippes (1905–1994). He was a diligent and meticulous worker, acknowledged for his work in orbit calculations and identifications of minor planets in widely separated oppositions.〔〔 == References ==
