Snellius Crater ( Latin Snellius ) is a large ancient impact crater in the southern hemisphere of the visible side of the Moon . The name was given in honor of the Dutch mathematician, physicist and astronomer Willebord Snell (Snellius) (1591-1626) and approved by the International Astronomical Union in 1935. The formation of the crater dates back to the Nectar period [1] .

Crater Description
The closest neighbors of Snellius Crater are Reichenbach Crater in the west-south-west; Borda Crater in the west-north-west; Rotsley Crater in the north; Petavius crater in the northeast; Haze Crater in the east; Furnner Crater in the southeast and Stevin Crater in the south-southwest. Along the crater, crossing its southwestern part, Snellius Valley passes [2] . Selenographic coordinates of the center of the crater , diameter 86.0 km [3] , depth 3830 m [4] .
Snellius Crater is close to circular with a small hollow in the western part and is almost completely destroyed. The shaft is almost equal to the surrounding area and turned into a ring of single ridges and hills, best preserved in the western part. The bottom of the bowl is crossed with the exception of the uplands of the flat northwestern part. South of the center of the bowl are several low parallel ridges.
