3960 Chaliubieju, provisional designation 1955 BG, is a stony asteroid from the central regions of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 20 January 1955, by astronomers at the Purple Mountain Observatory in Nanjing, China.[10] The asteroid was named after Cha Liubieju, a friend of one of the discoverers.[2]

Orbit and classification

Chaliubieju is an asteroid of the main belt's

background population that does not belong to any known asteroid family. It orbits the Sun in the central main-belt at a distance of 1.9–3.4 AU once every 4 years and 3 months (1,568 days). Its orbit has an eccentricity of 0.28 and an inclination of 14° with respect to the ecliptic.[1]

The asteroid was first identified as A921 EF at

Bergedorf Observatory in March 1921. The body's observation arc begins at Nanjing, two days after its official discovery observation.[10]

Physical characteristics

Chaliubieju is an assumed S-type asteroid.[3]

Diameter and albedo

According to the survey carried out by the

albedo between 0.288 and 0.34,[4][5][6] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.10 and calculates a diameter of 14.57 kilometers based on an absolute magnitude of 12.3.[3]
