It was discovered on 13 October 1966, by Russian astronomer Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula, who named after Soviet astronomer Andrei Severny.[2][26] Classification and orbitSeverny is a member of the Eos family. It orbits the Sun in the outer main-belt at a distance of 2.9–3.2 AU once every 5 years and 3 months (1,908 days). Its orbit has an eccentricity of 0.05 and an inclination of 9° with respect to the ecliptic. First identified as {{mp|1942 CA}} at Turku, the asteroid's first used observation was made at Heidelberg Observatory in 1950, extending Severny{{'}}s observation arc by 16 years prior to its official discovery observation.[26]Physical characteristicsSeverny has been characterized as a common stony S-type asteroid.[3]LightcurvesA rotational lightcurve of Severny was obtained by French amateur astronomer Laurent Bernasconi in March 2005. It gave a rotation period of 14.11 hours with a brightness variation of 0.14 magnitude ({{small|U=2}}).[11] In September 2013, photometric observations in the R-band at the Palomar Transient Factory, California, gave a shorter period of 9.2481 hours with an amplitude of 0.17 magnitude ({{small|U=2}}).[10] Diameter and albedoAccording to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Severny measures between 21.33 and 24.83 kilometers in diameter, and its surface has an albedo between 0.136 and 0.181.[5][7][8][9] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for Eoan asteroids of 0.14 and calculates a diameter of 21.40 kilometers with an absolute magnitude of 11.1.[3] NamingThis minor planet was named by the discoverer in honor of Soviet astronomer Andrei Severny (1913–1987), who was the Director of the Crimean Astrophysical Observatory[2] and known for his work on solar flares and astronomical observations from artificial satellites. The official naming citation was published by the Minor Planet Center before November 1977 ({{small|M.P.C. 2971}}).[38] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (1737) Severny |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 138 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_1738 |chapter = (1737) Severny }} [1][2][3][4][5][6][7][8][9][10][11]2. ^1 2 {{cite web |title = 1737 Severny (1966 TJ) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=1737 |accessdate = 21 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 = 21 December 2016}} 4. ^1 2 {{cite web |title = Asteroids and comets rotation curves – (1737) Severny |last = Behrend |first = Raoul |publisher = Geneva Observatory |url = http://obswww.unige.ch/~behrend/page4cou.html#001737 |accessdate = 21 December 2016}} 5. ^1 2 3 4 5 6 7 {{cite web |title = LCDB Data for (1737) Severny |publisher = Asteroid Lightcurve Database (LCDB) |url = http://www.minorplanet.info/PHP/GenerateALCDEFPage_Local.php?AstInfo=1737%7CSeverny |accessdate = 21 December 2016}} 6. ^1 2 3 4 {{cite journal |first1 = E.
