It was discovered by Japanese astronomer Tsutomu Seki at Geisei Observatory in Kōchi, Japan, on 21 February 1988.[12] The asteroid was later named after guitarist Andrés Segovia.[2] Orbit and classificationThe S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun in the inner main-belt at a distance of 2.0–2.5 AU once every 3 years and 5 months (1,249 days). Its orbit has an eccentricity of 0.12 and an inclination of 3° with respect to the ecliptic. It was first identified as {{mp|1962 ST}} at the Karl Schwarzschild Observatory in 1962, extending the body's observation arc by 26 years prior to its official discovery observation.[12] Physical characteristicsIn March 2016, a rotation period of Segovia was published using data from the Lowell Photometric Database (LPD). Using lightcurve inversion and convex shape models, as well as distributed computing power and the help of individual volunteers, a period of {{val|11.03204|0.00001}} hours could be obtained for this asteroid from the LPD's sparse-in-time photometry data ({{small|U=n.a.}}).[6] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of this orbital family – and calculates a diameter of 4.9 kilometers with an absolute magnitude of 13.7.[3] NamingThis minor planet was named for world-famous virtuoso classical guitarist Andrés Segovia (1893–1987). In 1959, the discoverer attended one of his concerts in Japan and became inspired to play the guitar.[2] The official naming citation was published by the Minor Planet Center on 21 April 1989 ({{small|M.P.C. 14481}}).[19] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (3822) Segovia |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 324 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_3815 |chapter = (3822) Segovia }} [1][2][3][4][5][6]2. ^1 2 {{cite web |title = 3822 Segovia (1988 DP1) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=3822 |accessdate = 12 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 = 12 May 2016}} 4. ^1 2 3 4 5 6 {{cite web |title = LCDB Data for (3822) Segovia |publisher = Asteroid Lightcurve Database (LCDB) |url = http://www.minorplanet.info/PHP/GenerateALCDEFPage_Local.php?AstInfo=3822%7CSegovia |accessdate = 12 May 2016}} 5. ^1 2 {{cite journal |first1 = J. |last1 = Durech |first2 = J. |last2 = Hanus |first3 = D. |last3 = Oszkiewicz |first4 = R. |last4 = Vanco |date = March 2016 |title = Asteroid models from the Lowell photometric database |url = http://adsabs.harvard.edu/cgi-bin/bib_query?bibcode=2016A&A...587A..48D |journal = Astronomy and Astrophysics |volume = 587 |page = 6 |bibcode = 2016A&A...587A..48D |doi = 10.1051/0004-6361/201527573 |arxiv = 1601.02909 |access-date= 12 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= 12 May 2016}} }} External links
