1631 Kopff, provisional designation 1936 UC, is a stony asteroid from the inner regions of the asteroid belt, about 9 kilometers in diameter. It was discovered by Finnish astronomer Yrjö Väisälä at Turku Observatory on 11 October 1936 ''(also see discovery circumstances below)''.〔 The asteroid is a member of the Flora family, a large group of stony S-type asteroids in the inner main-belt. It orbits the Sun at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,221 days). Its orbit shows an eccentricity of 0.21 and is tilted by 7 degrees to the plane of the ecliptic. It has a rotation period of 6.7 hours〔 and an albedo of 0.250, according to the surveys carried out by IRAS, Akari, and WISE/NEOWISE.〔〔〔 The minor planet was named after German astronomer August Kopff (1882–1960). He was first an assistant to Max Wolf prolific discoverer of minor planets himself. In 1924 he became Director of the Astronomisches Rechen-Institut in Berlin, and after the western section moved to Heidelberg he also became director of Heidelberg-Königstuhl Observatory. He was responsible for constructing the third Catalogue of Fundamental Stars (FK3) and initiated work on the fourth (FK4). The lunar carter Kopff is also named in his honour.〔 == Notes ==
