23131 Debenedictis, provisional designation Шаблон:Mp, is a bright background asteroid from the inner region of the asteroid belt, approximately 4 kilometers in diameter. It was discovered on 5 January 2000, by astronomers of the LINEAR program at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico, United States. The asteroid was named for 2007-ISEF awardee Erika Alden DeBenedictis.[1]
Orbit and classification
Debenedictis is a non-family from the main belt's background population.[2] It orbits the Sun in the inner asteroid belt at a distance of 1.9–2.6 AU once every 3 years and 4 months (1,220 days; semi-major axis of 2.23 AU). Its orbit has an eccentricity of 0.17 and an inclination of 2° with respect to the ecliptic.[3]
The body's observation arc begins with its first observations as Шаблон:Mp at Heidelberg Observatory in September 1955, or more than 44 years prior to its official discovery observation at Socorro.[1]
Physical characteristics
Based on the asteroid's geometric albedo of 0.249,[4] it is possibly a stony S-type asteroid.
Rotation period
As of 2018, no rotational lightcurve of Debenedictis has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown.[3][5]
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Debenedictis measures 3.853 kilometers in diameter and its surface has an albedo of 0.249.[4]
Naming
This minor planet was named after American 2007-ISEF awardee Erika Alden DeBenedictis (born 1992) for her computer science project. She attended the Saint Pius X High School, Albuquerque, New Mexico, United States. The official naming citation was published by the Minor Planet Center on 28 August 2007 (Шаблон:Small).[6]
In 2008, she further became connected to asteroids when she attended the Summer Science Program, which teaches astronomy through a curriculum based on asteroid observations and orbital calculations.[7] At the program in Socorro, New Mexico, just a short distance from where the asteroid was discovered, she had the opportunity to observe her namesake.[8]
