. It is largely degraded. Portions of the western and southwest rim still survive as low ridges in the surface, while the remainder is a jumble of irregular terrain with little definition. It was named after Polish astronomer Tadeusz Banachiewicz. Due to its location, this crater appears very foreshortened to an earthbound viewer. The visibility is more than partly affected by

as "Knox-Shaw"—lies on the eastern floor of the walled inner plain. It is located closer to the midpoint, and 12 km in circumference. It was named after British astronomer Harold Knox-Shaw. Knox-Shaw is a bowl-shaped formation of the type that is found over much of the lunar surface. The rim is circular and the inner walls slope down to a small interior floor at the midpoint. It is not significantly eroded and has no other distinguishing features. Just to the northeast of this formation is the large walled plain

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