Stevinus is a lunar

Moon

The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

Impact crater

In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body...

. To the southeast is the large crater Furnerius

Furnerius (crater)

Furnerius is a large lunar crater located in the southeast part of the Moon, in the area close to the southwestern limb. Because of its location, the crater appears oval in shape due to foreshortening but is actually nearly circular. Notable nearby craters include Stevinus to the northwest and...

. Just to the northeast is Snellius

Snellius (crater)

Snellius is a lunar crater located near the southeast limb of the Moon. Because of foreshortening the crater appears oval in shape, although it is actually nearly round. To the northeast is the large crater Petavius. South of Snellius is the crater Stevinus....

 and the Vallis Snellius

Vallis Snellius

Vallis Snellius is a linear valley on the near side of the Moon. It is located in the rugged southeastern part of the visible surface, to the south of the Mare Fecunditatis. This feature is radial to the Mare Nectaris basin to the west-northwest, much like Vallis Rheita to the southwest, and the...

 crater valley. To the west-northwest lies Reichenbach

Reichenbach (crater)

Reichenbach is a crater in the rugged southeastern part of the Moon's near side. It is located to the west-northwest of the prominent crater Stevinus, and to the west of Snellius....

. To the west-northwest of Stevinus is the tiny crater Stevinus A, a feature that possesses a small ray system

Ray system

A ray system comprises radial streaks of fine ejecta thrown out during the formation of an impact crater, looking a bit like many thin spokes coming from the hub of a wheel. The rays can extend for lengths up to several times the diameter of their originating crater, and are often accompanied by...

Albedo

Albedo , or reflection coefficient, is the diffuse reflectivity or reflecting power of a surface. It is defined as the ratio of reflected radiation from the surface to incident radiation upon it...

.

Stevinus has a high inner wall and a central peak at the mid-point of the interior floor. The inner walls are slumped, so that the side slopes down sharply, then more gradually. There are several small ridges on the floor, in addition to the peak. Stevinus is from the Copernican period, which lasted from 1.1 billion years ago until the present. It is named for Simon Stevin

Simon Stevin

Simon Stevin was a Flemish mathematician and military engineer. He was active in a great many areas of science and engineering, both theoretical and practical...

, a 16th-century Belgian mathematician and engineer.

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 Stevinus.
