Galois (crater)
 Galois is a large lunar crater on the far side of the Moon. Features of this class are commonly termed walled plains due to their appearance and dimension. It is located just to the southeast of another huge walled plain Korolev a formation nearly double the diameter of Galois. Several hundred kilometers due south is another enormous feature Apollo.This is a heavily eroded feature with a rim that has been reshaped by impacts particularly along the northwest edge where it lies near Korolev.
