It was discovered by Slovak astronomers Adrián Galád and Alexander Pravda at Modra Observatory on 23 March 1997.[12] It was named after Paula Pravdová ("Pajka"), the daughter of the second discoverer.[2] Orbit and classificationPajka is a non-family asteroid from the main belt's background population. It orbits the Sun in the inner asteroid belt at a distance of 2.0–2.8 AU once every 3 years and 9 months (1,372 days). Its orbit has an eccentricity of 0.16 and an inclination of 9° with respect to the ecliptic.The body's observation arc begins 6 years prior to its official discovery observation, with a precovery taken at Steward Observatory (Kitt Peak–Spacewatch) in October 1991.[12] NamingThis minor planet was named after Paula Pravdová (born 1990), whose familiar name is "Pajka". She is the daughter of the discovering astronomer Alexander Pravda and often visited Modra Observatory.[2] The official naming citation was published by the Minor Planet Center on 28 March 2002 ({{small|M.P.C. 45234}}).[17] Physical characteristicsA rotational lightcurve of Pajka was obtained from photometric observations made by the discovering astronomer at Modra Observatory in January 2008. The lightcurve showed a rotation period of {{val|3.9428}} hours with a brightness amplitude of 0.21 in magnitude ({{small|U=3-}}).[6] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 4.3 kilometers with an absolute magnitude of 14.2.[3] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (12482) Pajka |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 783 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_8612 |chapter = (12482) Pajka }} [1][2][3][4][5][6]2. ^1 2 {{cite web |title = 12482 Pajka (1997 FG1) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=12482 |accessdate = 19 May 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 = 19 May 2016}} 4. ^1 2 3 4 5 6 {{cite web |title = LCDB Data for (12482) Pajka |publisher = Asteroid Lightcurve Database (LCDB) |url = http://www.minorplanet.info/PHP/GenerateALCDEFPage_Local.php?AstInfo=12482%7CPajka |accessdate = 19 May 2016}} 5. ^1 2 {{Cite journal |first1 = Adrian |last1 = Galad |first2 = Leonard |last2 = Kornos |date = October 2008 |title = A Collection of Lightcurves from Modra: 2007 December- 2008 June |url = http://adsabs.harvard.edu/cgi-bin/bib_query?bibcode=2008MPBu...35..144G |journal = The Minor Planet Bulletin |volume = 35 |issue = 4 |pages = 144–146 |issn = 1052-8091 |bibcode = 2008MPBu...35..144G |access-date= 19 May 2016}} 6. ^1 {{cite journal |display-authors = 6 |first1 = Peter |last1 = Veres |first2 = Robert |last2 = Jedicke |first3 = Alan |last3 = Fitzsimmons |first4 = Larry |last4 = Denneau |first5 = Mikael |last5 = Granvik |first6 = Bryce |last6 = Bolin |first7 = Serge |last7 = Chastel |first8 = Richard J. |last8 = Wainscoat |first9 = William S. |last9 = Burgett |first10 = Kenneth C. |last10 = Chambers |first11 = Heather |last11 = Flewelling |first12 = Nick |last12 = Kaiser |first13 = Eugen A. |last13 = Magnier |first14 = Jeff S. |last14 = Morgan |first15 = Paul A. |last15 = Price |first16 = John L. |last16 = Tonry |first17 = Christopher |last17 = Waters |date = November 2015 |title = Absolute magnitudes and slope parameters for 250,000 asteroids observed by Pan-STARRS PS1 - Preliminary results |url = http://adsabs.harvard.edu/cgi-bin/bib_query?bibcode=2015Icar..261...34V |journal = Icarus |volume = 261 |pages = 34–47 |bibcode = 2015Icar..261...34V |doi = 10.1016/j.icarus.2015.08.007 |arxiv = 1506.00762 |access-date= 19 May 2016}} }} External links
