Eponym	John H. Poynting

Poynting is a large lunar impact crater that is located on the far side of the Moon. It is located to the north-northwest of the Hertzsprung walled-plain, with Fersman crater just to the east and Kekulé crater equally near to the west-southwest.

This crater has undergone some erosion, and several small craters lie across the rim and inner wall. A pair of these lie next to each other along the eastern side, and another pair on the western rim. Across the southeast rim is a nearly merged crater pair. Parts of the rim remain well-defined, however, including the east and north where there are some terraces. The rim is generally circular, with a slight inward intrusion along the northwest.

The interior floor is relatively level, except for a central peak ridge located slightly to the east of the mid-point. There are small craterlets on the floor near the south and northwest edge, and a number of tiny craterlets.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Poynting crater.
