The rim of Nernst is relatively well-defined, although several smaller impacts lies across the edge. The satellite crater 'Nernst T' has broken through the western rim edge. Smaller craters also lie aling the rim to the southwest and south-southeast. Around the remainder of the inner wall is some slumping and a few terrace-like features.
The interior of Nernst is relatively level, with a central peak formation offset slightly to the south of the mid-point. A pair of small craters lie on the interior floor along the western and southern inner edges. Parts of the remaining floor are marked by a series of rilles. In the southern half these rilles form grooves running generally from east to west.
