This crater has a sharp-edged and somewhat irregular rim that appears polygonal more than circular. There are terraces along the inner sides, with some slumping along the northern and western inner edge. The south-southwestern part of the rim is overlaid by the smaller crater Newcomb A. The interior floor is uneven, particularly near the rim of Newcomb A. Just to the south-southeast of the crater is the satellite crater Newcomb J. This feature is named after the American astronomer Simon Newcomb.[1]

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 Newcomb.
