eponym=Giovanni B. ZupiZupus is the
lava -flooded remains of a lunar crater. It is located on a southwestern reach of theOceanus Procellarum , to the northwest ofMare Humorum . To the north-northeast is the flooded Billy crater, and some distance to the southeast is the Mersenius crater. A system of faintrille s named the Rimae Zupus lie to the northwest, following a coarse to the north-northwest toward the "maria".Little remains of the original formation, and the rim is low and irregular in outline—giving the feature the appearance of a valley. This rim climbs to a maximum height of 1.3 km above the base. The crater Zupus S intrudes upon the eastern rim. A faint ghost-crater lies in the "maria" to the northeast. The "maria" covering the Zupus crater floor is darker in hue than the surrounding terrain, making the feature relatively easy for an observer to locate.

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 Zupus crater.
