Shi Shen (crater)

It lies to the northwest of the large walled plain Schwarzschild, and to the south-southeast of the crater Nansen along the north-northeastern limb.

This is an old, eroded crater with an outer rim that is rounded and somewhat irregular.

The northern part of the rim has a wider inner wall, and there is a small crater along the north-northwestern edge.

The interior floor is relatively level, but uneven, particularly in the northern half.

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