3412 Kafka, provisional designation , is an asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 10 January 1983, by American astronomers Randolph Kirk and Donald Rudy at Palomar Observatory in California, United States. The asteroid was named after writer Franz Kafka.
Orbit and classification
Kafka 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 at the Finnish Turku Observatory in 1942, extending the body's observation arc by 41 years prior to its official discovery observation at Palomar.
Physical characteristics
According 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. Kafka is a superslow rotator. Its rotation period of 2,766 hours (about 115 days) is among the longest of any known asteroid.
Naming
This 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. The approved naming citation was published by the Minor Planet Center on 13 February 1987 (M.P.C. 11641).
