4776 Luyi, provisional designation Template:Mp, is a bright background asteroid from the inner regions of the asteroid belt, approximately Script error: No such module "convert". in diameter. It was discovered on 3 November 1975, by Harvard astronomers at the Oak Ridge Observatory in Massachusetts, United States. The asteroid was named for the Chinese town of Luyi, birthplace of Laozi who founded Taoism.[1] Luyi is also named after the son of Harvard astronomer Cheng-yuan Shao.[1]

Orbit and classification

Luyi is a non-family asteroid from the main belt's background population.[2] It orbits the Sun in the inner asteroid belt at a distance of 1.8–2.9 AU once every 3 years and 6 months (1,286 days; semi-major axis of 2.31 AU). Its orbit has an eccentricity of 0.23 and an inclination of 5° with respect to the ecliptic.[3] The body's observation arc begins with its first and official discovery observation at Oak Ridge.[1]

Physical characteristics

The asteroid has an absolute magnitude of 14.3.[3] Its spectral type is unknown. Based on its high albedo (see below), Luyi is a bright asteroid of the S-complex. As of 2018, no rotational lightcurve has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown.[3]

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 3.645 kilometers in diameter and its surface has a high albedo of 0.30.[4]

Naming

This minor planet was named after a town in the eastern Henan province of China that was the birthplace of Laozi, founder of Taoism, because long-time participant in Harvard's minor-planet program, astronomer Cheng-yuan Shao (born 1927), came from that town (also see 1881 Shao). The asteroid is also named after his son, Luyi.[1]

The official naming citation was published by the Minor Planet Center on 21 November 1991 (M.P.C. 19339Script error: No such module "Check for unknown parameters".).[5]
