It was discovered by Serbian astronomer Milorad Protić at Belgrade Astronomical Observatory, Serbia, on 6 September 1940.[24] It was named for the former country of Yugoslavia.[2] Orbit and classificationThe asteroid is a member of the Eunomia family, a large group of mostly stony S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun in the central main-belt at a distance of 2.1–3.1 AU once every 4 years and 3 months (1,548 days). Its orbit has an eccentricity of 0.20 and an inclination of 12° with respect to the ecliptic. Yugoslavia was first identified as {{mp|1932 YA}} at Uccle Observatory in 1932. Its observation arc begins 4 year prior to its official discovery observation, with a precovery taken at Nice Observatory in 1936.[24] Physical characteristicsFrom 2007 to 2012, several photometric lightcurve observations of Yugoslavia established a well-defined rotation period of 3.89 hours with a brightness variation between 0.64 and 0.74 magnitude ({{small|U=3/3/3}}).[10][11][12] According to the surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Yugoslavia measures between 14.73 and 21.39 kilometers in diameter, and its surface has an albedo between 0.070 and 0.269.[5][7][8][9] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.21 – derived from 15 Eunomia, the family's largest member and namesake – and calculates a diameter of 15.94 kilometers with an absolute magnitude of 11.3.[3] NamingThis minor planet was named after the former country of Yugoslavia.[2] The approved naming citation was published by the Minor Planet Center before November 1977 ({{small|M.P.C. 2277}}).[37] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (1554) Yugoslavia |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 123 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_1555 |chapter = (1554) Yugoslavia }} [1][2][3][4][5][6][7][8][9][10][11]2. ^1 2 {{cite web |title = 1554 Yugoslavia (1940 RE) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=1554 |accessdate = 30 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 = 30 December 2016}} 4. ^1 2 3 {{cite journal |display-authors = 6 |first1 = Joseph R. |last1 = Masiero |first2 = T. |last2 = Grav |first3 = A.
