It was discovered on 10 January 1983, by American astronomers Randolph Kirk and Donald Rudy at Palomar Observatory in California, United States.[7]{{sfn|Edberg|Levy|1994|p=80}} The asteroid was named after writer Franz Kafka.[2] Orbit and classificationKafka orbits the Sun in the inner main-belt at a distance of 2.0–2.5 AU once every 3 years and 4 months (1,212 days). Its orbit has an eccentricity of 0.10 and an inclination of 3° with respect to the ecliptic. It was first identified as {{mp|1942 YB}} at the Finnish Turku Observatory in 1942, extending the body's observation arc by 41 years prior to its official discovery observation at Palomar.[7]Physical characteristicsAccording to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Kafka measures 6.1 kilometers in diameter and its surface has an albedo of 0.231.[4] As of 2017, its rotation period and shape remain unknown.[13] NamingThis minor planet was named after Franz Kafka (1883–1924), Austrian–Czech writer of novels and short stories, in which protagonists are faced with bizarre or surrealistic situations.[2] The approved naming citation was published by the Minor Planet Center on 13 February 1987 ({{small|M.P.C. 11641}}).[15] References1. ^1 2 3 {{cite book |title = Dictionary of Minor Planet Names – (3412) Kafka |last = Schmadel | first = Lutz D. |publisher = Springer Berlin Heidelberg |page = 284 |date = 2007 |isbn = 978-3-540-00238-3 |doi = 10.1007/978-3-540-29925-7_3412 |chapter = (3412) Kafka }} [1][2][3][4][5]2. ^1 2 {{cite web |title = 3412 Kafka (1983 AU2) |work = Minor Planet Center |url = http://www.minorplanetcenter.net/db_search/show_object?object_id=3412 |accessdate = 5 December 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 = 5 December 2016}} 4. ^1 2 3 {{cite journal |display-authors = 6 |first1 = Joseph R. |last1 = Masiero |first2 = T. |last2 = Grav |first3 = A.
