    1650 Heckmann, provisional designation 1937 TG, is a dark asteroid from the inner regions of the asteroid belt, about 30 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 11 October 1937.[10]

    The asteroid is a member of the Polanian subgroup of the Nysa family of asteroids and shows a rare F-type spectrum in the Tholen classification scheme. It orbits the Sun at a distance of 2.0–2.8 AU once every 3 years and 10 months (1,389 days). It takes about of 14.9 hours to rotate around its axis[7][8][9] and has a low albedo in the range of 0.03 to 0.05, according to the IRAS, Akari and WISE/NEOWISE surveys.[4][5][6]

    It was named in honor of German astronomer Otto Heckmann (1901–1983), director of the Bergedorf Observatory in Hamburg, president of the International Astronomical Union (1967–1970) and the first director of ESO, the European Southern Observatory, which foundation had been initiated by him. He was active in the fields of cosmology and several aspects of fundamental astronomy.[2]
