Schiller est un cratère de 179 sur 71 Km et profond de 3900 m situé dans le Sud-ouest de la Lune. À l'est on trouve le cratère Golfeer (47 Km) et au Nord-est Schiller H. La muraille de Schiller a une forme ovale. L’axe, le plus long, se trouve suivant une ligne Nord-ouest sud-est. Schiller semble être une fusion de deux cratères ou plus. La muraille du cratère est bien définie, avec un mur intérieur en terrasse et un léger rempart externe. Le fond est plat, inondé par la lave avec quelques taches blanches. Une ligne de crête s’étire dans la partie Nord-ouest du plancher. Entre Schiller et Bailly au Sud, on peut apercevoir un bassin d’impact à anneau multiples, anonyme, dont la surface est relativement lisse découvert dans les années 1960 par Bill Hartmann et Gerard Kuiper. Les trois anneaux ont des diamètres respectifs de 335, 175 et 85 km.

 Schiller is an oddly-shaped lunar impact crater located in the southwest sector of the moon. To the east is the Bayer crater and to the southeast is Rost crater.
The rim of Schiller has an elongated shape that is amplified by its proximity to the lunar limb. The long axis lies along a line running northwest-southeast, with the wider girth located in the southeastern half. There is a slight bend in the elongation, with the concave side facing to the northeast. Observers have noted that Schiller appears to be a fusion of two or more craters. It bears a superficial resemblance to the footprint left by a shoe.
The crater rim is well-defined, with a terraced inner wall and a slight outer rampart. At the southeast end, a smaller crater is connected to Schiller by a wide valley. Most of the Schiller crater floor is flat, most likely due to lava flooding. There are some bright patches that are most clearly visible under a high sun angle. A double-ridge lies along the center of the northwest crater floor, forming a nearly linear formation that divides the floor in half.
Southwest of Schiller is an unnamed area of maria. It is speculated that this is the remains of an ancient formation that has had its outer walls completely eroded away. This basin has received the unofficial designation 'Schiller Annular Plain' among lunar observers.
