Zucchius is a prominent lunar impact crater located near the southwest limb. Because of its location the crater appears oblong-shaped due to foreshortening. It lies just to the south-southwest of Segner crater, and northeast of the much larger Bailly walled-plain. To the southeast is the Bettinus crater, a formation only slightly larger than Zucchius.
The crater rim is symmetrical and shows little significant wear from impacts. The inner wall is terraced, and there is a group of small central peaks that forms a curving arc around the middle of the floor. This crater is believed to have formed during the Copernician period, within the last 1.2 thousand million years.
