“1918 Aiguillon”的意思、由来-开放百科全书

According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Aiguillon measures 19.5 kilometers in diameter, and its surface has an albedo of 0.062.^[4]

Based on a generic magnitude-diameter conversion, the body measures between 12 and 28 kilometers, for an albedo in the range of 0.05 to 0.25 and an absolute magnitude of 11.7.^[5] As of 2017, Aiguillon{{'}}s composition, rotation period and shape remain unknown.^[14]

Naming

This minor planet was named for the discoverer’s birthplace, Aiguillon, a small town on the Garonne river in France.^[2] The approved naming citation was published by the Minor Planet Center on 1 December 1979 ({{small|M.P.C. 5038}}).^[16]

It was discovered by French astronomer Guy Soulié at Bordeaux Observatory, France, on 19 October 1968.^[8] The asteroid was named for the French town of Aiguillon.^[2] Orbit and classification Aiguillon orbits the Sun in the outer main-belt at a distance of 2.8–3.6 AU once every 5 years and 9 months (2,085 days). Its orbit has an eccentricity of 0.13 and an inclination of 9° with respect to the ecliptic. The first observation was a precovery taken at Palomar Observatory in 1954, extending the body's observation arc by 14 years prior to its official discovery observation.^[8] Physical characteristics According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Aiguillon measures 19.5 kilometers in diameter, and its surface has an albedo of 0.062.^[4] Based on a generic magnitude-diameter conversion, the body measures between 12 and 28 kilometers, for an albedo in the range of 0.05 to 0.25 and an absolute magnitude of 11.7.^[5] As of 2017, Aiguillon{{'}}s composition, rotation period and shape remain unknown.^[14] Naming This minor planet was named for the discoverer’s birthplace, Aiguillon, a small town on the Garonne river in France.^[2] The approved naming citation was published by the Minor Planet Center on 1 December 1979 ({{small\|M.P.C. 5038}}).^[16] References 1. ^¹²³{{cite book \|title = Dictionary of Minor Planet Names – (1918) Aiguillon \|last = Schmadel \| first = Lutz D. \|publisher = Springer Berlin Heidelberg \|page = 154 \|date = 2007 \|isbn = 978-3-540-00238-3 \|doi = 10.1007/978-3-540-29925-7_1919 \|chapter = (1918) Aiguillon }} 2. ^¹²{{cite web \|title = 1918 Aiguillon (1968 UA) \|work = Minor Planet Center \|url = http://www.minorplanetcenter.net/db_search/show_object?object_id=1918 \|accessdate = 10 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 = 10 December 2016}} 4. ^¹²{{cite web \|title=Absolute Magnitude (H) \|publisher=NASA/JPL \|url=http://neo.jpl.nasa.gov/glossary/h.html \|accessdate=2 January 2016}} 5. ^¹{{cite web \|title = LCDB Data for (1918) Aiguillon \|publisher = Asteroid Lightcurve Database (LCDB) \|url = http://www.minorplanet.info/PHP/GenerateALCDEFPage_Local.php?AstInfo=1918%7CAiguillon \|accessdate = 11 April 2017}} 6. ^¹²³{{cite journal \|display-authors = 6 \|first1 = Joseph R. \|last1 = Masiero \|first2 = T. \|last2 = Grav \|first3 = A.
