Zach is a lunar impact crater located in the heavily-cratered southern sector of the moon. To the north is Lilius crater, while to the southeast is Pentland and to the south the larger Curtius crater. Due to foreshortening, the crater has an oblong appearance when viewed from Earth.
The inner walls of the crater are prominently terraced, while parts of the outer wall are indented by lesser craters. There are adjacent craters attached to the northeast, southwest, and southern parts of the rim. There is also a pair of overlapping craters on the northwest rim. The bottom is relatively flat with a few craterlets and a double central peak offset to the north.

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 Zach crater.
