 that is covered in overlapping crater impacts. It is joined at the southeast rim by the smaller crater Barocius

Barocius (crater)

Barocius is an ancient lunar impact crater that is located in the rugged southern highlands of the Moon. It lies just to the southeast of the large crater Maurolycus. To the southwest of Barocius is Clairaut, and to the south-southeast lies Breislak....

. Due west lie the overlapping pair of Stöfler

Stöfler (crater)

Stöfler is a large lunar impact crater located in the crater-riddled southern highlands, named for Johannes Stöffler. It sits to the west of the crater Maurolycus. The distorted crater Fernelius is attached to the northern rim, and Miller and Nasireddin lie to the west...

 and Faraday

Faraday (crater)

Faraday is a lunar impact crater in the southern highlands of the Moon. It lies across the southeast rim of the larger crater Stöfler, and the northwest rim of Faraday forms a wide rampart across the otherwise flat floor of Stöfler...

. To the northeast is the faint crater Buch

Buch (crater)

Buch is an old, worn crater that is located in the rugged southern highlands of the Moon. It lies to the northeast of the large crater Maurolycus, and the comparably sized crater Büsching is attached to the northeast rim....

Gemma Frisius (crater)

Gemma Frisius is a lunar crater that is located in the rugged southern highlands of the Moon. It lies to the north of the walled plain Maurolycus, and southeast of the smaller crater Poisson. The crater Goodacre is attached to the northeast rim....

.

The outer walls of Maurolycus are tall, wide, and terraced, most notably in the eastern part. To the southeast the rim is lower and the crater is joined to what has the appearance of an overlain crater rim. The crater Maurolycus F lies across the northwest rim, and that part of the crater floor is more rugged than the remainder. The other sections of the floor are relatively level, with a complex of central peaks and a pair of craterlets. The small crater Maurolycus A is biting into the southern part of the rim.

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 Maurolycus.
