14871 Pyramus, provisional designation 1990 TH7, is a dark Zhongguo
Pyramus from classical mythology.[2]
Orbit and classification
Pyramus is a non-
It orbits the Sun in the
semi-major axis of 3.3 AU). Its orbit has an eccentricity of 0.22 and an inclination of 1° with respect to the ecliptic.[3] The first precovery was taken at Palomar Observatory in 1954, extending the asteroid's observation arc by 36 years prior to its discovery.[1]
Physical characteristics
Diameter and albedo
According to the survey carried out by NASA's
albedo of 0.069.[7] This is in line with a generic absolute magnitude-to-diameter conversion that gives a diameter of 4 to 9 kilometers for an albedo between 0.05 and 0.25.[6]
