flows or ejecta, leaving a relatively flat surface that is marked only by tiny craters and a slight wrinkle ridge down the middle. The northern half is rugged and irregular, with the satellite crater Newton D overlying the north-northeastern rim and extending across nearly half the crater diameter. The rim in the south is relatively low and narrow, with the smaller crater Newton G partly overlain and flooded by lava. This adjacent crater forms a step up from the interior of Newton, and there is a tiny

in the south floor of Newton where it appears as if a channel flowed down the side from Newton G. The other parts of the outer crater wall are much wider than in the south end, particularly in the areas adjacent to Newton D.

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 Newton.
