1985 Hopmann, provisional designation 1929 AE, is an asteroid in the asteroid belt about 36 kilometers in diameter. It was discovered on January 13, 1929 by astronomer Karl Reinmuth at Heidelberg Observatory, Germany.〔 The asteroid orbits the Sun at a distance of 2.6–3.6 AU every five and a half years (2,016 days). It has a geometric albedo of 0.07.〔 Photometric measurements made from the Oakley Southern Sky Observatory during 2012 gave a light curve with a period of hours and a variation in brightness of in magnitude. Within the margin of error, this result is consistent with a synodic period estimate of hours made in by an independent investigator.〔 The asteroid is named after astronomer Josef Hopmann (1890–1975), who was director of Vienna Observatory (1951–1962), an active observer of binary and variable stars, and a participant in the international program to observe 433 Eros during 1930/31.〔 The lunar crater ''Hopmann'' is also named in his honour. == References ==
