Chang Heng (crater)
lunar impact crater
Chang Heng is a degraded lunar impact crater that is located on the Moon's far side. It lies less than one crater diameter to the northeast of the walled plain Fleming. The rim of Chang Heng is eroded, with a pair of small craters along the northern rim and tiny craters along the south and east edges. The interior floor contains a small, concentric crater that is about one third the diameter of Chang Heng.
The crater is named after Chinese astronomer Zhang Heng (78–139). This designation was formally adopted by the International Astronomical Union in 1970.
