Zucchius is a prominent lunar impact crater located near the southwestern limb. Because of its location the crater appears oblong-shaped due to foreshortening. It lies just to the south-southwest of the crater Segner, and northeast of the much larger walled plain Bailly. To the southeast is Bettinus, 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. Due to its ray system, Zucchius is mapped as part of the Copernican System.
To the northeast of Zucchius is the Schiller-Zucchius Basin, a Pre-Nectarian basin (multi-ringed impact structure). This basin has received the unofficial designation 'Schiller Annular Plain' among lunar observers.
