4760 Jia-xiang, provisional designation Шаблон:Mp, is a background asteroid from the inner regions of the asteroid belt, approximately Шаблон:Convert in diameter. It was discovered on 1 April 1981, by astronomers at Harvard University's Oak Ridge Observatory in Massachusetts, United States.[1] The presumed stony S-type asteroid was named after Chinese astronomer Zhang Jiaxiang. It has a rotation period of 14.96 hours.Шаблон:EfnШаблон:Efn

Orbit and classification

Jia-xiang is a non-family asteroid from the main belt's background population.[2] It orbits the Sun in the inner main-belt at a distance of 2.0–2.6 AU once every 3 years and 7 months (1,296 days; semi-major axis of 2.33 AU). Its orbit has an eccentricity of 0.13 and an inclination of 10° with respect to the ecliptic.[3] The body's observation arc begins with a precovery taken at Palomar Observatory in January 1955, or 26 years prior to its official discovery observation at Oak Ridge.[1]

Physical characteristics

Rotation period

In 2017, two rotational lightcurves of Jia-xiang were obtained from photometric observations by Czech astronomer Petr Pravec at Ondřejov Observatory. Lightcurve analysis gave a rotation period of 14.96 and 14.9601 hours with a brightness amplitude of 0.55 and 0.63 magnitude, respectively (Шаблон:Small).Шаблон:EfnШаблон:Efn

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Jia-xiang measures between 4.79 and 5.16 kilometers in diameter and its surface has an albedo between 0.13 and 0.2275.[4][5][6][7]

The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.20 and calculates a diameter of 4.71 kilometers based on an absolute magnitude of 14.0.[8]

Naming

This minor planet was named after Chinese astronomer Zhang Jiaxiang (born 1932).[1] The official naming citation was published by the Minor Planet Center on 21 November 1991 (Шаблон:Small).[9]
