19763 Klimesh (provisional designation2000 MC) is a stony Phocaeaasteroid andslow rotator from the inner regions of theasteroid belt, approximately 7 kilometers in diameter. Discovered byNEAT atHaleakala Observatory in 2000, the asteroid was named for NEAT's software specialist Matthew Klimesh.[2]
Klimesh was discovered on 18 June 2000, by NASA's and JPL'sNear-Earth Asteroid Tracking program (NEAT) with theMaui Space Surveillance System (MSSS) at theHaleakala Observatory site on the island of Maui, Hawaii, in the United States.[11] The body'sobservation arc begins 15 years prior to its official discovery observation, with aprecovery from theDigitized Sky Survey taken at the AustralianSiding Spring Observatory in September 1985.[11]
This asteroid is a member of thePhocaea family (701),[4] a group of asteroids with similar orbital characteristics. It orbits the Sun in theinner main-belt at a distance of 1.9–2.9 AU once every 3 years and 8 months (1,350 days). Its orbit has aneccentricity of 0.20 and aninclination of 23° with respect to theecliptic.[1]
Klimesh has been characterized as a stonyS-type asteroid.[3] It possibly rotates chaotically.[3]
Klimesh is aslow rotator, as it has arotation period of 101 hours with a brightness variation of0.67magnitude. The photometric observations were made by Czech astronomerPetr Pravec at theOndřejov Observatory during the asteroid's 2011-opposition (U=2).[a]
The result supersedes a period of 4.4 hours with an amplitude of 0.12, obtained from a fragmentarylightcurve by Italian astronomerSilvano Casulli (U=1).[9]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer, Klimesh has a diameter of 5.65 and 7.27 kilometers with analbedo of 0.24 and 0.175, respectively.[5][6][7] TheCollaborative Asteroid Lightcurve Link adopts Petr Pravec's revised WISE-data, that is, an albedo of 0.1635 and a diameter of 7.29 kilometers with anabsolute magnitude of 13.27.[3][8]
Thisminor planet was named afterJPL researcher Matthew Klimesh (born 1968), developer of the compression algorithm used for handling the vast amount of data obtained by the discovering NEAT program. Since 1996 at JPL's Communications Systems and Research Section, his work includes data compression,rate–distortion theory andchannel coding.[2] The official naming citation was published by theMinor Planet Center on 9 May 2001 (M.P.C. 42677).[12]
