19738 Calinger ( provisional designation 2000 AS97) is a background asteroid from the inner regions of the asteroid belt, approximately 3 kilometers in diameter.
It was discovered on 4 January 2000, by members of the Lincoln Near-Earth Asteroid Research team at Lincoln Laboratory's Experimental Test Site in Socorro, New Mexico, and named after DCYSC-mentor Manetta Calinger. [2] [4]
Calinger is a non- family asteroid from the main belt's background population. It orbits the Sun in the inner asteroid belt at a distance of 1.9–2.7 AU once every 3 years and 5 months (1,260 days). Its orbit has an eccentricity of 0.18 and an inclination of 8 ° with respect to the ecliptic. [1]
The body's observation arc begins almost 10 years prior to its official discovery observation, with a precovery from the Digitized Sky Survey taken at Palomar Observatory in May 1990. [4]
According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Calinger measures 3.272 kilometers in diameter and its surface has a high albedo of 0.314. [3] It has an absolute magnitude of 14.1. [1]
As of 2017, Calinger's rotation period and shape remain unknown. [1] [5]
This minor planet was named after Manetta Calinger who mentored a finalist in the 2003 Discovery Channel Youth Science Challenge, DCYSC. [2] The approved naming citation was published by the Minor Planet Center on 10 October 2003 ( M.P.C. 49772). [6]
