Discovered by Joseph Hunaerts in 1936, it was named after Belgian astronomer Pol Swings. DiscoverySwings was discovered on 28 August 1936, by Belgian astronomer Joseph Hunaerts at the Royal Observatory of Belgium in Uccle, Belgium.[8] In the following month, it was independently discovered by astronomer Cyril Jackson at Johannesburg Observatory in South Africa.[2]Orbit and classificationThe 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. In 1907, Swings was first identified as {{mp|1907 YT}} at Heidelberg Observatory. However, the body's observation arc begins with its official discovery observation at Uccle in 1936.[8] Physical characteristicsAccording 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.[4][5] It has an absolute magnitude of 10.4. As of 2017, the body's spectral type, rotation period and shape remain unknown. NamingThis 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 before November 1977 ({{small|M.P.C. 3932}}).[17] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (1637) Swings |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 130 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_1638 |chapter = (1637) Swings }} [1][2][3][4][5]2. ^1 2 {{cite web |title = 1637 Swings (1936 QO) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=1637 |accessdate = 27 December 2016}} 3. ^1 {{cite web |title = MPC/MPO/MPS Archive |work = Minor Planet Center |url = http://www.minorplanetcenter.net/iau/ECS/MPCArchive/MPCArchive_TBL.html |accessdate = 27 December 2016}} 4. ^1 2 {{cite journal |first1 = E.
