It was discovered on 20 March 1955, by the Slovakian astronomers Alois Paroubek and Regina Podstanická at Skalnate Pleso Observatory, Slovakia, and named for the High Tatra Mountains.[2][27] It was their only minor planet discovery. Orbit and classificationBased on its orbital elements, the asteroid is a member of the Vesta family and classified as a carbonaceous C-type asteroid in the SMASS taxonomy. It orbits the Sun in the inner main-belt at a distance of 2.2–2.5 AU once every 3 years and 7 months (1,317 days). Its orbit has an eccentricity of 0.08 and an inclination of 8° with respect to the ecliptic. It was first identified as {{mp|1935 UQ}} at the South African Union Observatory in 1935, extending the asteroid's observation arc by 20 years prior to its official discovery.[27] Diameter and albedoAccording to the surveys carried out by the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures between 8.99 and 9.87 kilometers in diameter and its surface has an albedo between 0.175 and 0.262.[5][6][7][8] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a much larger diameter of 16.8 kilometers, as the lower the albedo (reflectivity), the higher the diameter at a constant absolute magnitude (brightness).[3] LightcurvesPhotometric measurements of the asteroid made in January 2005, by astronomer Brian D. Warner at his Palmer Divide Observatory, Colorado, gave a lightcurve with a period of {{val|39.9|0.1}} hours and a brightness variation of below {{val|0.22 |0.02}} in magnitude. However, the data was incomplete, so the period is considered suspect ({{small|U=2-}}).[11] Further measurements made in October 2007, by Adrián Galád, Leonard Kornoš and Štefan Gajdoš at Modra Observatory in Slovakia, showed a much longer period of {{val|131.3|0.2}} hours with a brightness variation of 0.5 in magnitude ({{small|U=2}}).[12] In March 2009, a fragmentary lightcurve obtained by French amateur astronomer Pierre Antonini gave a period of 24 hours ({{small|U=1}}).[10]TumblerThe observers also detected a non-principal axis rotation seen in distinct rotational cycles in successive order. This is commonly known as tumbling.[3][12][40] Tatry is one of a group of less than 200 bodies known to be is such a state (also see List of tumblers). NamingThis minor planet is named after the location of the discovering observatory, High Tatras ({{lang-cz|Vysoké Tatry}}), the highest mountain range in northern Slovakia.[2] The approved naming citation was published by the Minor Planet Center on 1 February 1980 ({{small|M.P.C. 5183}}).[42] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (1989) Tatry |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 161 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_1990 |chapter = (1989) Tatry }} [1][2][3][4][5][6][7][8][9][10][11][12][13]2. ^1 2 {{cite web |title = 1989 Tatry (1955 FG) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=1989 |accessdate = 2 November 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 = 2 November 2016}} 4. ^1 2 {{cite web |title = Asteroids and comets rotation curves – (1989) Tatry |last = Behrend |first = Raoul |publisher = Geneva Observatory |url = http://obswww.unige.ch/~behrend/page4cou.html#001989 |accessdate = 2 November 2016}} 5. ^1 2 3 {{Cite journal |display-authors = 6 |first1 = Joseph R. |last1 = Masiero |first2 = A.
