2752 Wu Chien-Shiung, provisional designation 1965 SP, is an Eoan
rotation period of 36.3 hours.[3] It was named for Chinese-American nuclear physicist Chien-Shiung Wu.[1]
Orbit and classification
Wu Chien-Shiung is a core member of the
semi-major axis of 3.02 AU). Its orbit has an eccentricity of 0.11 and an inclination of 10° with respect to the ecliptic.[2]
The asteroid was first observed as 1933 QW at
Heidelberg Observatory in August 1933. The body's observation arc begins as 1960 VA at the Goethe Link Observatory in November 1960, or 5 years prior to its official discovery observation at Nanking.[1]
Physical characteristics
Wu Chien-Shiung is an assumed

In August 2012, a rotational
U=2).[8] While not being a slow rotator
with spin rates above 100 hours, Wu Chien-Shiung's period is significantly longer than the average 2 to 20 hours observed for most asteroids.
Diameter and albedo
According to the surveys carried out by the Japanese
albedo of 0.203 and 0.184,[5][6][7] respectively, while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for K-type asteroids of 0.14 – derived from the Eos family's parent body – and calculates a diameter of 17.80 kilometers based on an absolute magnitude of 11.5.[3]
Naming
This
uranium isotopes by gaseous diffusion and for the Wu experiment conducted in 1956, for which she was awarded a Wolf Prize in Physics in 1978 (also see list of laureates).[1]
The official naming citation was published by the
M.P.C. 16040).[10]
