It was discovered by Belgian astronomer Eric Elst at ESO's La Silla Observatory in Northern Chile, on 19 November 1990.[18] The asteroid was named for Belgian painter Alfred Stevens.[2] Orbit and classificationBased on its orbital elements, Alfredstevens is a member of the Vesta family, a group of asteroids that originated from a massive impact on the Southern Hemnisphere of 4 Vesta, the family's namesake. It orbits the Sun in the inner main-belt at a distance of 2.1–2.6 AU once every 3 years and 7 months (1,324 days). Its orbit has an eccentricity of 0.12 and an inclination of 6° with respect to the ecliptic. The body's observation arc begins just five days prior to its official discovery observation, with a precovery taken at Palomar Observatory on 14 November 1990.[18] Physical characteristicsLightcurvesIn January 2013, a rotational lightcurve of Alfredstevens 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|4.2993}} hours with a brightness variation of 0.45 magnitude ({{small|U=2}}).[8] Diameter and albedoAccording to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, Alfredstevens measures 2.6 kilometers in diameter and its surface has a high albedo of 0.34,[5][6] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a larger diameter of 3.1 kilometers with an absolute magnitude of 14.93.[3] NamingThis minor planet was named in honor of Belgian painter Alfred Stevens (1823–1906), known for his paintings of elegant modern women.[2] The official naming citation was published by the Minor Planet Center on 30 January 2010 ({{small|M.P.C. 68446}}).[27] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (13058) Alfredstevens |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 835 |date = 2003 |url = https://books.google.ch/books?id=aeAg1X7afOoC&pg=PA835 |isbn = 978-3-540-29925-7 |accessdate = 12 May 2016}} [1][2][3][4][5][6][7][8]2. ^1 2 {{cite web |title = 13058 Alfredstevens (1990 WN3) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=13058 |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 (13058) Alfredstevens |publisher = Asteroid Lightcurve Database (LCDB) |url = http://www.minorplanet.info/PHP/GenerateALCDEFPage_Local.php?AstInfo=13058%7CAlfredstevens |accessdate = 12 May 2016}} 5. ^1 2 3 4 {{cite journal |display-authors = 6 |first1 = A. |last1 = Mainzer |first2 = T. |last2 = Grav |first3 = J. |last3 = Masiero |first4 = E. |last4 = Hand |first5 = J. |last5 = Bauer |first6 = D. |last6 = Tholen |first7 = R.
