The assumed S-type asteroid was discovered on 9 November 1999, by American amateur astronomer Charles W. Juels at the Fountain Hills Observatory {{Obscode|678}} in Arizona, United States.[1] It has a rotation period of 15.9 hours and was named after Australian amateur astronomer John Broughton.[2] Orbit and classificationBroughton is non-family asteroid from the main belt's background population,[5][6] located near the region occupied by the Flora family, one of the largest clans of stony asteroids. It orbits the Sun in the inner asteroid belt at a distance of 2.2–2.4 AU once every 3 years and 7 months (1,308 days; semi-major axis of 2.34 AU). Its orbit has an eccentricity of 0.04 and an inclination of 7° with respect to the ecliptic.The asteroid was first observed as {{mp|1997 BV|6}} at the Japanese Tajimi Observatory {{Obscode|901}} in January 1997, where its observation arc begins in the following month, about 2 years prior to the asteroid's official discovery observation at Fountain Hills.[1] NamingThis minor planet was named in honor of Australian amateur astronomer John Broughton (born 1952), a prolific discoverer of minor planets who received a "Shoemaker NEO Grant" in 2002.[2] The approved naming citation was published by the Minor Planet Center on 26 November 2004 ({{small|M.P.C. 53176}}).[25] Physical characteristicsLightcurvesIn October 2013, a rotational lightcurve of Broughton was obtained from photometric observations in the R-band by astronomers at the Palomar Transient Factory in California. Lightcurve analysis gave a rotation period of {{val|15.9442}} hours with a brightness variation of 0.34 magnitude ({{small|U=2}}).[9] Diameter and albedoThe Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the family's largest member and namesake – and calculates a diameter of 3.65 kilometers with an absolute magnitude of 14.36.[8] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (24105) Broughton, Addendum to Fifth Edition: 2003–2005 |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 186 |date = 2006 |isbn = 978-3-540-34361-5 |doi = 10.1007/978-3-540-34361-5_2178 |chapter = (24105) Broughton [2.34, 0.04, 7.3] }} [1][2][3][4][5][6][7]2. ^1 2 3 4 5 {{cite web |title = 24105 Broughton (1999 VE10) |work = Minor Planet Center |url = https://www.minorplanetcenter.net/db_search/show_object?object_id=24105 |accessdate = 17 July 2018}} 3. ^1 {{cite web |title = MPC/MPO/MPS Archive |work = Minor Planet Center |url = https://www.minorplanetcenter.net/iau/ECS/MPCArchive/MPCArchive_TBL.html |accessdate = 31 July 2016}} 4. ^1 2 {{cite web |title = Asteroid (24105) Broughton – Proper elements |publisher = AstDyS-2, Asteroids – Dynamic Site |url = http://hamilton.dm.unipi.it/astdys/index.php?n=24105&pc=1.1.6 |accessdate = 17 July 2018}} 5. ^1 2 {{cite web |title = Asteroid 24105 Broughton |work = Small Bodies Data Ferret |url = https://sbntools.psi.edu/ferret/SimpleSearch/results.action?targetName=24105+Broughton |accessdate = 17 July 2018}} 6. ^1 2 3 4 5 {{cite web |title = LCDB Data for (24105) Broughton |publisher = Asteroid Lightcurve Database (LCDB) |url = http://www.minorplanet.info/PHP/GenerateALCDEFPage_Local.php?AstInfo=24105%7CBroughton |accessdate = 31 July 2016}} 7. ^1 2 3 {{Cite journal |display-authors = 6 |first1 = Adam |last1 = Waszczak |first2 = Chan-Kao |last2 = Chang |first3 = Eran O. |last3 = Ofek |first4 = Russ |last4 = Laher |first5 = Frank |last5 = Masci |first6 = David |last6 = Levitan |first7 = Jason |last7 = Surace |first8 = Yu-Chi |last8 = Cheng |first9 = Wing-Huen |last9 = Ip |first10 = Daisuke |last10 = Kinoshita |first11 = George |last11 = Helou |first12 = Thomas A. |last12 = Prince |first13 = Shrinivas |last13 = Kulkarni |date = September 2015 |title = Asteroid Light Curves from the Palomar Transient Factory Survey: Rotation Periods and Phase Functions from Sparse Photometry |journal = The Astronomical Journal |volume = 150 |issue = 3 |page = 35 |bibcode = 2015AJ....150...75W |doi = 10.1088/0004-6256/150/3/75 |arxiv = 1504.04041 }} }} External links
