3537 Jürgen, provisional designation1982 VT, is a stony Eunomiaasteroid from the middle region of theasteroid belt, approximately 8 kilometers in diameter. It was discovered by American astronomerEdward Bowell at Lowell'sAnderson Mesa Station, Arizona, on 15 November 1982.[8] It was named after planetary scientistJürgen Rahe.[2]
Jürgen is both a member of theEunomia andMaria family of asteroids.[4] It orbits the Sun in thecentral main-belt at a distance of 2.2–3.0 AU once every 4 years and 2 months (1,520 days). Its orbit has aneccentricity of 0.16 and aninclination of 15° with respect to theecliptic.[1] The firstprecovery was taken atCrimea-Nauchnij in 1982, extending the asteroid'sobservation arc by just 25 days prior to its discovery.[8]
Jürgen is a commonS-type asteroid.[3] It has also been characterized as a rare LS-type byPan-STARRS' large-scale photometric survey.[7]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer, the asteroid measures 7.8 and 8.3 kilometers in diameter and its surface has analbedo of 0.168 and 0.188,[5][6] while theCollaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.21 and hence calculates a larger diameter of 9.1 kilometers.[3]
A 2004-published photometriclightcurve analysis by Brazilian astronomer Alvaro Alvarez-Candal rendered a provisionalrotation period of 14 hours with a brightness amplitude of 0.3 inmagnitude (U=1).[4]
Thisminor planet was named after Jürgen Rahe (1939–1997), German planetary scientist, astrophysicist, and Director for Solar System Exploration at NASA's Office of Space Science.[9] He is best known for his cometary atlases and observations using theInternational Ultraviolet Explorer.
Jürgen Rahe was also a principal investigator of theInternational Halley Watch (IHW), director of both, the astronomy department atFAU and theDr. Remeis Observatory, and affiliated withIAU'sPhysical Studies of Comets, Minor Planets and Meteorites commission for many years. His diplomatic skills in international projects were beneficial to both IHW and IAU.[2] The approved naming citation was published by theMinor Planet Center on 2 April 1988 (M.P.C. 12973).[10]
