3181 Ahnert
3181 Ahnert, provisional designation , is a stony Flora asteroid from the inner regions of the asteroid belt, about 8 kilometers in diameter. It was discovered by German astronomer Freimut Börngen at the Karl Schwarzschild Observatory in Tautenburg, eastern Germany, on 8 March 1964. Orbit and classification The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun in the Kirkwood gap, inner main-belt at a distance of 2.1–2.4 Astronomical unit, AU once every 3 years and 4 months (1,216 days). Its orbit has an orbital eccentricity, eccentricity of 0.07 and an orbital inclination, inclination of 4Degree (angle), ° with respect to the ecliptic. The first precovery was obtained at Lowell Observatory in 1931, extending the asteroid's observation arc by 33 years prior to its discovery. Physical characteristics According to the surveys carried out by NASA's space-based Wide-field Infrared Survey Exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freimut Börngen
Freimut Börngen (; 17 October 1930 – 19 June 2021) was a German astronomer and a prolific discoverer of minor planets. A few sources give his first name wrongly as "Freimuth". The Minor Planet Center credits him as F. Borngen. He studied galaxies with the Schmidt telescope at the Karl Schwarzschild Observatory in Tautenburg, Germany. In 1995 he retired, but continued to work as a freelancer for the observatory. As a by-product of his work, he discovered numerous asteroids (519, ). The research on asteroids had to be done in his spare time, as the search for small objects was not considered prestigious enough by the East Germany, GDR research managers. During the GDR regime, Börngen restricted himself to politically neutral names for his asteroids, such as topics related to Thuringia or famous scientists and composers. Examples include 2424 Tautenburg, 3181 Ahnert, 3245 Jensch, or 3941 Haydn. After the German reunification, he chose systematically historical, cultural, scienti ...
