14871 Pyramus, provisional designation 1990 TH7, is a dark Zhongguo asteroid from the outermost region of the asteroid belt, approximately 9 kilometers (6 miles) in diameter. It was discovered on 13 October 1990 by German astronomers Lutz Schmadel and Freimut Börngen at the Karl Schwarzschild Observatory in Tautenburg, Germany.[1] The asteroid was named for Pyramus from classical mythology.[2]

Pyramus is a non-family asteroid from the main belt’s background population. It is a member of the small group of Zhongguo asteroids, located in the 2 : 1 mean motion resonance with the giant planet Jupiter. Contrary to the nearby unstable Griqua group, the orbits of the Zhongguos are stable over half a billion years.[4][5][8]
It orbits the Sun in the outer main-belt at a distance of 2.6–4.0 AU once every 6.00 years (2,192 days; 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]
