It was discovered on 11 September 1942, by astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in southwest Germany.[1] The S-type asteroid has a longer-than average rotation period of 29.3 hours.[20] It was named for German astrophysicist Hans Kienle.[2] Orbit and classificationKienle is a non-family asteroid from the main belt's background population.[5][6] It orbits the Sun in the central asteroid belt at a distance of 1.8–3.5 AU once every 4 years and 4 months (1,577 days; semi-major axis of 2.65 AU). Its orbit has an eccentricity of 0.31 and an inclination of 5° with respect to the ecliptic. The body's observation arc begins at with its official discovery observation during the height of World War II on September 1942.[1]NamingThis minor planet was named after German astrophysicist Hans Kienle (1895–1975), known for his work on spectrophotometry and director of several German observatories, including the discovering Heidelberg Observatory (1950–1962). Kienle was also president of IAU Commission 36 during the 1950s.[2] The official {{MoMP|1759|naming citation}} was published by the Minor Planet Center before November 1977 ({{small|M.P.C. 4155}}).[29] Physical characteristicsIn both the Tholen- and SMASS-like taxonomy of the Small Solar System Objects Spectroscopic Survey (S3OS2), Kienle is a stony S-type asteroid.[5][15] Rotation periodDuring the early 1980s, a rotational lightcurve of Kienle was obtained from photometric observations by American astronomer Richard Binzel using the 0.91- and 2.1-meter telescopes at the University of Texas McDonald Observatory. Lightcurve analysis gave a rotation period of 29.25 hours with a brightness amplitude of 0.30 magnitude ({{small|U=2}}).[20][11] Diameter and albedoAccording to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Kienle measures between 6.9 and 7.3 kilometers in diameter and its surface has an albedo between 0.18 and 0.20.[8][9][10] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.10 – a compromise figures between the stony inner- and carbonaceous outer-belt asteroids – and consequently calculates a larger diameter of 9.85 kilometers based on an absolute magnitude of 13.15.[20] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (1759) Kienle |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 140 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_1760 |chapter = (1759) Kienle }} [1][2][3][4][5][6][7][8][9][10][11]2. ^1 2 3 4 5 {{cite web |title = 1759 Kienle (1942 RF) |work = Minor Planet Center |url = https://www.minorplanetcenter.net/db_search/show_object?object_id=1759 |accessdate = 10 December 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 = 10 December 2018}} 4. ^1 2 {{cite web |title = Asteroid (1759) Kienle – Proper elements |publisher = AstDyS-2, Asteroids – Dynamic Site |url = http://hamilton.dm.unipi.it/astdys/index.php?n=1759&pc=1.1.6 |accessdate = 10 December 2018}} 5. ^1 2 3 {{cite web |title = Asteroid 1759 Kienle |work = Small Bodies Data Ferret |url = https://sbntools.psi.edu/ferret/SimpleSearch/results.action?targetName=1759+Kienle |accessdate = 10 December 2018}} 6. ^1 2 3 {{cite journal |display-authors = 6 |first1 = Joseph R. |last1 = Masiero |first2 = A.
