1637 Swings, provisional designation 1936 QO, is a dark asteroid from the outer region of the asteroid belt, about 45 kilometers in diameter. It was discovered by Belgian astronomer Joseph Hunaerts at the Royal Observatory of Belgium in Uccle on 28 August 1936.[3] In the following month, it was independently discovered by astronomer Cyril Jackson in Johannesburg, South Africa.[2]
The asteroid orbits the Sun at a distance of 2.9–3.2 AU once every 5.38 years (1,965 days). Its orbit shows an eccentricity of 0.04 and is tilted by 14 degrees to the plane of the ecliptic. It has a low geometric albedo of 0.042, based on observations carried out by the Infrared Astronomical Satellite, IRAS.[1] Its rotation period is still to be determined.
The asteroid was named after Belgian astrophysicist and astronomer Pol Swings (1906–1983), president of the International Astronomical Union during 1964–1967, who significantly contributed to the understanding of the physics of comets and their spectra.[2]
