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.
