It was discovered on 16 August 1925, by Soviet astronomer Grigory Shajn at Simeiz Observatory on the Crimean peninsula.[24] It was named in honor of Ukraine.[2] Orbit and classificationUkraina orbits the Sun in the inner main-belt at a distance of 1.9–2.9 AU once every 3 years and 8 months (1,340 days). Its orbit has an eccentricity of 0.21 and an inclination of 8° with respect to the ecliptic.The body's observation arc begins at Heidelberg, five days after its official discovery observation at Simeiz.[24] Physical characteristicsThe S-type asteroid has an albedo of about 0.2[6] and a rotation period of 7.3 hours.[9][10] NamingThis minor planet was named after the country Ukraine, then the Ukrainian Soviet Socialist Republic (1922–1991). The name was proposed by the Institute of Theoretical Astronomy in Leningrad, what is now St. Petersburg.[2] The official naming citation was published by the Minor Planet Center before November 1977 ({{small|M.P.C. 2740}}).[32] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (1709) Ukraina |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 136 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_1710 |chapter = (1709) Ukraina }} [1][2][3][4][5][6][7][8][9][10]2. ^1 2 {{cite web |title = 1709 Ukraina (1925 QA) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=1709 |accessdate = 18 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 = 18 December 2016}} 4. ^1 2 {{cite web |title = Asteroids and comets rotation curves – (1709) Ukraina |last = Behrend |first = Raoul |publisher = Geneva Observatory |url = http://obswww.unige.ch/~behrend/page4cou.html#001709 |accessdate = 18 December 2016}} 5. ^1 2 3 4 5 {{cite web |title = LCDB Data for (1709) Ukraina |publisher = Asteroid Lightcurve Database (LCDB) |url = http://www.minorplanet.info/PHP/GenerateALCDEFPage_Local.php?AstInfo=1709%7CUkraina |accessdate = 18 December 2016}} 6. ^1 2 3 {{cite journal |display-authors = 6 |first1 = Fumihiko |last1 = Usui |first2 = Daisuke |last2 = Kuroda |first3 = Thomas G. |last3 = Müller |first4 = Sunao |last4 = Hasegawa |first5 = Masateru |last5 = Ishiguro |first6 = Takafumi |last6 = Ootsubo |first7 = Daisuke |last7 = Ishihara |first8 = Hirokazu |last8 = Kataza |first9 = Satoshi |last9 = Takita |first10 = Shinki |last10 = Oyabu |first11 = Munetaka |last11 = Ueno |first12 = Hideo |last12 = Matsuhara |first13 = Takashi |last13 = Onaka |date = October 2011 |title = Asteroid Catalog Using Akari: AKARI/IRC Mid-Infrared Asteroid Survey |url = http://pasj.oxfordjournals.org/content/63/5/1117.full.pdf+html |journal = Publications of the Astronomical Society of Japan |volume = 63 |issue = 5 |pages = 1117–1138 |bibcode = 2011PASJ...63.1117U |doi = 10.1093/pasj/63.5.1117 |access-date= 18 December 2016}} 7. ^1 2 3 4 {{cite journal |display-authors = 6 |first1 = Joseph R. |last1 = Masiero |first2 = A.
