It was discovered on 2 March 1989, by Belgian astronomer Eric Elst at the La Silla Observatory in northern Chile.[18] It was named for ESO staff member Elisabeth Völk.[2] Classification and orbitVölk is a stony S-type asteroid and core member of the Vesta family,[3] one of the largest families in the inner asteroid belt. It orbits the Sun at a distance of 2.0–2.6 AU once every 3 years and 6 months (1,278 days). Its orbit has an eccentricity of 0.14 and an inclination of 6° with respect to the ecliptic. The first precovery was taken at Palomar Observatory in 1973, extending the asteroid's observation arc by 16 years prior to its discovery.[18]LightcurveIn September 2015, a rotational lightcurve was constructed from photometric observations by American astronomer Robert D. Stephens at the Center for Solar System Studies in California. It showed a well-defined rotation period of {{val|2.896|0.001}} hours with a brightness amplitude of 0.18 in magnitude ({{small|U=3}}).[8] DiameterAccording to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 4.0 kilometers in diameter and its surface has an outstandingly high albedo of 0.44,[5][6] while the Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.24 – in accordance with the family's largest member and namesake, 8 Flora – and calculates a diameter of 5.2 kilometers.[7] The body's S-type spectrum has also been determined in the large-scale survey performed by Pan-STARRS.[13] NamingThis minor planet was named after Elisabeth Völk (born 1946), administrative staff member at ESO's headquarters in Germany, in charge of the ESO Schmidt plates archive, who became a good friend of the discoverer. The naming was independently suggested by astronomer and author of the Dictionary of Minor Planets, Lutz Schmadel.[2] The approved naming citation was published by the Minor Planet Center on 15 February 1995 ({{small|M.P.C. 24766}}).[29] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (6189) Völk |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 516 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_5706 |chapter = (6189) Völk }} [1][2][3][4][5][6][7][8][9]2. ^1 2 {{cite web |title = 6189 Volk (1989 EY2) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=6189 |accessdate = 14 April 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 = 17 May 2016}} 4. ^1 2 {{cite web |title = Asteroid (6189) Volk |publisher = AstDyS-2, Asteroids – Dynamic Site |url = http://hamilton.dm.unipi.it/astdys/index.php?n=6189&pc=1.1.6 |accessdate = 23 July 2018}} 5. ^1 2 3 4 5 {{cite web |title = LCDB Data for (6189) Volk |publisher = Asteroid Lightcurve Database (LCDB) |url = http://www.minorplanet.info/PHP/GenerateALCDEFPage_Local.php?AstInfo=6189%7CVolk |accessdate = 14 April 2016}} 6. ^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.
