1739 Meyermann, provisional designation 1939 PF, is a stony asteroid from the inner regions of the asteroid belt, about 8 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 15 August 1939.[6]
The asteroid is a member of the Flora family, a large group of S-type asteroids in the inner main-belt. It orbits the Sun at a distance of 2.0–2.5 AU once every 3.40 years (1,241 days). Its orbit shows an eccentricity of 0.12 and is inclined by 3 degrees to the plane of the ecliptic. It has a rotation period of 2.822 hours and an albedo of 0.20 and 0.37, according to preliminary results from the surveys carried out by the WISE and NEOWISE missions, respectively.[4][5]
The minor planet was named in memory of Bruno Meyermann (1876–1963), a classical astronomer and academic teacher at Göttingen Observatory in Lower Saxony, Germany. His fields of interest included polar motion and relativistic effects.[2]
