It was discovered on 3 April 1940, by Finnish astronomer Yrjö Väisälä at Turku Observatory in Southwest Finland,[16] and named after American astronomer Carl Hergenrother in 1996.[2] Orbit and classificationHergenrother orbits the Sun in the outer main-belt at a distance of 2.3–3.5 AU once every 4 years and 11 months (1,786 days). Its orbit has an eccentricity of 0.20 and an inclination of 15° with respect to the ecliptic. The body's observation arc begins 6 days after its official discovery observation at Turku.[16]Physical characteristicsRotation periodIn January 2008, a rotational lightcurve of Hergenrother was obtained from photometric observations by French amateur astronomer Pierre Antonini. Lightcurve analysis gave a rotation period of 24.266 hours with a brightness variation of 0.28 magnitude ({{small|U=2}}).[8] Diameter and albedoAccording to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Hergenrother measures 14.73 kilometers in diameter and its surface has an albedo of 0.224,[5][6] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and consequently calculates a diameter of 29.21 kilometers, as the lower the albedo, the larger the body's diameter at a certain absolute magnitude.[3] NamingThis minor planet was named in honor of American astronomer Carl W. Hergenrother (born 1973). At Lunar and Planetary Laboratory, he has been a discoverer of minor planets with high inclinations during the Bigelow Sky Survey, precursor to the Catalina Sky Survey. The naming was proposed by MPC director Brian G. Marsden among others.[2] The official naming citation was published by the Minor Planet Center on 3 May 1996 ({{small|M.P.C. 27124}}).[25] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (3099) Hergenrother |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 255 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_3100 |chapter = (3099) Hergenrother }} [1][2][3][4][5][6][7]2. ^1 2 {{cite web |title = 3099 Hergenrother (1940 GF) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=3099 |accessdate = 8 March 2017}} 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 = 8 March 2017}} 4. ^1 2 {{cite web |title = Asteroids and comets rotation curves – (3099) Hergenrother |last = Behrend |first = Raoul |publisher = Geneva Observatory |url = http://obswww.unige.ch/~behrend/page4cou.html#003099 |accessdate = 8 March 2017}} 5. ^1 2 3 {{cite journal |display-authors = 6 |first1 = Joseph R. |last1 = Masiero |first2 = A.
