Stevinus (75 km), is an impact crater on the south-east of the Moon, and is 3 km deep. Southeast is the great crater Furnerius (125 miles), and north-east is Snellius (83 km). To the northwest is Reichenbach (71 km).
Stevinus has a high interior wall and a central peak in mid. There are several small increases on the floor, in addition to the central peak. The crater is dating from the Copernican period, which lasted from 1.1 billion years ago until now. It is named after Simon Stevin, a belgian mathematician and engineer of the 16th century.
Snellius (83 km), it is not too far from Stevinus. On north-east is the huge crater Petavius (177 km), which is seen in the pictures above only partially (the south).
Snellius's edge is eroded, with some small overlapping craters. The floor is irregular and uneven. Western edge marks the beginning of Snellius Vallis, one of the longest valley of the Moon. It has about 500 km heading north-west almost to the Nectaris sea's edge. Its origin is associated with the formation of this sea.
