It was discovered on 26 October 1971, by Czech astronomer Luboš Kohoutek at Bergedorf Observatory in Hamburg, Germany.[26] The asteroid was named after the first President of Czechoslovakia, Tomáš Garrigue Masaryk.[2] Orbit and classificationMasaryk orbits the Sun in the outer main-belt at a distance of 3.1–3.8 AU once every 6 years and 4 months (2,311 days). Its orbit has an eccentricity of 0.10 and an inclination of 3° with respect to the ecliptic. First identified as {{mp|1936 FW}} at Uccle Observatory, Masaryk{{'}}s first used observation was taken at Goethe Link Observatory in 1955, extending the body's observation arc by 16 years prior to its official discovery observation.[26]Physical characteristicsThe carbonaceous asteroid is characterized as a (darker) P-type and as a transitional CX-type by NEOWISE and PanSTARRS, respectively.[5][18] Rotation periodIn April 2006, a rotational lightcurve of Masaryk was obtained from photometric observations made by French amateur astronomer Pierre Antonini. It gave a rotation period of 7.53 hours with a brightness variation of 0.52 magnitude ({{small|U=2+}}).[10] The result agrees with a lightcurve published in March 2016, using sparse-in-time photometry data from the Lowell Photometric Database ({{small|U=n.a.}}).[11] 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, Masaryk measures between 38.6 and 46.1 kilometers in diameter, and its surface has an albedo between 0.039 and 0.057.[5][6][7][9] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.036 and a diameter of 46.0 kilometers with an absolute magnitude of 10.9.[8] NamingThis minor planet was named in honor of the first president of the independent Czechoslovak Republic, Tomáš Garrigue Masaryk (1850–1937), statesman, philosopher and known for his humanistic ideas.[2] The official naming citation was published by the Minor Planet Center before November 1977 ({{small|M.P.C. 3757}}).[40] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (1841) Masaryk |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 147 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_1842 |chapter = (1841) Masaryk }} [1][2][3][4][5][6][7][8][9][10][11]2. ^1 2 {{cite web |title = 1841 Masaryk (1971 UO1) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=1841 |accessdate = 14 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 = 14 December 2016}} 4. ^1 2 {{cite web |title = Asteroids and comets rotation curves – (1841) Masaryk |last = Behrend |first = Raoul |publisher = Geneva Observatory |url = http://obswww.unige.ch/~behrend/page4cou.html#001841 |accessdate = 14 December 2016}} 5. ^1 2 3 4 5 {{cite web |title = LCDB Data for (1841) Masaryk |publisher = Asteroid Lightcurve Database (LCDB) |url = http://www.minorplanet.info/PHP/GenerateALCDEFPage_Local.php?AstInfo=1841%7CMasaryk |accessdate = 14 December 2016}} 6. ^1 2 3 4 {{cite journal |first1 = E.
