Why can we not see the South Pole-Aitken basin from Earth? The moon rotates too fast to see any surface features.
The sun never shines on that side of the moon, so the crater is always in shadow.
The crater is too small to see from Earth.
The crater is on the far side of the moon, which we cannot see.
