6376 Schamp, provisional designation1987 KD1, is a stony backgroundasteroid from the central regions of theasteroid belt, approximately 8 kilometers (5 miles) in diameter. It was discovered on 29 May 1987, by American astronomer coupleCarolyn andEugene Shoemaker at thePalomar Observatory in California.[1] TheS-type asteroid has arotation period of 6.6 hours.[6] It was named afterLarry and Becky Schamp who took care of the Shoemaker family afterEugene's fatal car accident in Australia.[1]
Schamp is a non-family asteroid from the main belt'sbackground population.[3] It orbits the Sun in thecentral main-belt at a distance of 1.9–3.2 AU once every 4 years and 2 months (1,509 days;semi-major axis of 2.58 AU). Its orbit has aneccentricity of 0.25 and aninclination of 16° with respect to theecliptic.[2] The body'sobservation arc begins with its first observation as1971 SG at theLeoncito Astronomical Complex in September 1971, almost 16 years prior to its official discovery observation at Palomar.[1]
Schamp has been characterized as a common, stonyS-type asteroid byPan-STARRS' survey and in theSDSS-based taxonomy.[6][8][9]
In July 2012, two rotationallightcurves ofSchamp were obtained fromphotometric observations byPetr Pravec andRobert Stephens. Lightcurve analysis gave a well-definedrotation period of 6.6093 and 6.613 hours with an identical brightness amplitude of 0.16magnitude (U=3/3).[6][7][a]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Schamp measures 7.924 kilometers in diameter and its surface has analbedo of 0.213,[4][5] while theCollaborative Asteroid Lightcurve Link assumes a standard albedo for a stony asteroid of 0.20 and calculates a diameter of 8.18 kilometers based on anabsolute magnitude of 12.8.[6]
Thisminor planet was named after Americans stationed inAlice Springs, Larry and Becky Schamp, who cared for members of the Shoemaker family after an automobile accident in whichEugene Shoemaker died in 1997.[1] The official naming citation was published by theMinor Planet Center on 11 April 1998 (M.P.C. 31610).[10]
