Steno is a relatively small lunar impact crater that is located in the northern hemisphere on the Moon's far side. It lies to the south-southwest of the slightly larger crater Stearns, a much younger and less worn formation. Farther to the northwest of Steno is Appleton, and to the east is Nušl.

The crater is named after the Danish astronomer Nicolas Steno. It was officially named by the IAU in 1970 along with many other prominent far side craters.[1]

This is a worn crater formation that has a circular outer rim that remains relatively well-defined. The rim edge is marked only by a few tiny craterlets. The interior floor and inner walls are nearly featureless, except for a few faint groove marks and some tiny craterlets. It is otherwise an undistinguished formation.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Steno.
