9902 Kirkpatrick, provisional designation Шаблон:Mp, is a Florian asteroid from the inner regions of the asteroid belt, approximately 4 kilometers in diameter. The asteroid was discovered on 3 July 1997, by American amateur astronomer Paul Comba at Prescott Observatory in Arizona, United States, and named after American musician Ralph Kirkpatrick.[1]
Orbit and classification
Kirkpatrick is a member of the Flora family. It orbits the Sun in the inner main-belt at a distance of 2.0–2.4 AU once every 3 years and 3 months (1,200 days). Its orbit has an eccentricity of 0.08 and an inclination of 5° with respect to the ecliptic.[2] It was first identified as Шаблон:Mp at El Leoncito in 1988, extending the asteroid's observation arc by 9 years prior to its official discovery at Prescott.[1]
Physical characteristics
Rotation period
As of 2017, the asteroid's rotation period and shape remain unknown.[3]
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite IRAS and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Kirkpatrick measures 17.8 and 3.611 kilometers in diameter, respectively.[4][5] WISE/NEOWISE also gives an albedo of 0.179 for the body's surface.[4] It has an absolute magnitude of 14.4.[2]
Naming
This minor planet was named after Ralph Kirkpatrick (1911–1984), an American musician, musicologist and harpsichordist. He has written a biography of Domenico Scarlatti and published a chronological catalog of his keyboard sonatas (also see Шаблон:MoMP). Kirkpatrick studied 17th and 18th century performance practices in chamber music and gave concerts playing the works by Scarlatti and Bach (also see Шаблон:MoMP).[6] The official naming citation was published by the Minor Planet Center on 2 April 1999 (Шаблон:Small).[7]
