    1780 Kippes, provisional designation A906 RA, is a stony asteroid from the outer region of the asteroid belt, about 28 kilometers in diameter. It was discovered by German astronomer August Kopff at Heidelberg Observatory on 12 September 1906.[9]

    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[8] and an albedo of about 0.12, according to the surveys carried out by IRAS, Akari, WISE and NEOWISE.[4][5][6][7]

    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.[2][10]
