Discovery edit
Swings was discovered on 28 August 1936, by Belgian astronomer Joseph Hunaerts at the Royal Observatory of Belgium in Uccle, Belgium.[5] In the following month, it was independently discovered by astronomer Cyril Jackson at Johannesburg Observatory in South Africa.[2]
Orbit and classification edit
The asteroid orbits the Sun in the outer main-belt at a distance of 2.9–3.2 AU once every 5 years and 5 months (1,967 days). Its orbit has an eccentricity of 0.04 and an inclination of 14° with respect to the ecliptic.[1] In 1907, Swings was first identified as 1907 YT at Heidelberg Observatory. However, the body's observation arc begins with its official discovery observation at Uccle in 1936.[5]
Physical characteristics edit
According to the surveys carried out by the Infrared Astronomical Satellite IRAS and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Swings' surface has an albedo of 0.042, and measures 45.15 and 52.99 kilometers in diameter, respectively.[3][4] It has an absolute magnitude of 10.4.[1]
As of 2017, the body's spectral type, rotation period and shape remain unknown.[1]
Naming edit
This minor planet was named after Pol Swings (1906–1983), a Belgian astrophysicist, astronomer and president of the International Astronomical Union during 1964–1967, who significantly contributed to the understanding of the physics of comets and their spectra.[2] The official naming citation was published by the Minor Planet Center on 20 February 1976 (M.P.C. 3932).[6]
