17683 Kanagawa (provisional designation1997 AR16) is a carbonaceous backgroundasteroid from the outer region of theasteroid belt, approximately 22 kilometers (14 miles) in diameter. It was discovered on 10 January 1997, by Japanese astronomerAtsuo Asami at theHadano Observatory, located 60 kilometers southwest of Tokyo, Japan.[1] The asteroid was later named after the JapaneseKanagawa Prefecture.[2]
Kanagawa orbits the Sun in theouter main-belt at a distance of 2.5–3.5 AU once every 5 years and 2 months (1,882 days). Its orbit has aneccentricity of 0.16 and aninclination of 18° with respect to theecliptic.[4] Noprecoveries were taken prior to its discovery. The asteroid'sobservation arc begins with its official discovery observation at Hadano.[1]
Thisminor planet was named after the JapaneseKanagawa Prefecture, in which the city ofHadano with its discovering observatory is located. Also located in the east of Kanagawa Prefecture, are the industrial cities ofYokohama andKawasaki, the second and ninth biggest city of the country, respectively, and vital centers of Japan's economy. The discoverer, Atsuo Asami, graduated atKanagawa University.[2] The official naming citation was published by theMinor Planet Center on 9 March 2001 (M.P.C. 42365).[8]
In October 2009, a rotationallightcurve of Kanagawa was obtained at theWise Observatory in Israel. The photometric observations rendered a well-definedrotation period of5.895±0.004 hours with a brightness variation of 0.4magnitude (U=3).[7]
According to the space-based surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite, and NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission, Kanagawa has a lowalbedo between 0.030 and 0.062, and a diameter of 16.8 to 22.1 kilometers.[4][5][6] TheCollaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, and derives acarbonaceous albedo of 0.033 with a diameter of 22.1 kilometers and anabsolute magnitude of 12.6.[3]
