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.〔 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.〔〔 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.〔 == References ==
