Eponym Edmond Halley
Halley is a lunar impact crater that is intruding into the southern wall of the Hipparchus walled-plain. To the southwest of Halley is the large Albategnius crater, and due east lies the slightly smaller Hind crater.

The rim of Halley crater is somewhat worn, and a scar in the lunar surface passes through the western rim, forming a valley that runs to the south-southeast, near the rim of Albetagnius. The interior floor of Halley is relatively flat.

Satellite craters

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 Halley crater.
