That’s not the issue. The artist has decided that the cutout is the shadow, and just made ot “move across” the moon. This is now how light hitting the moon looks from Earth.

@agamemnonymous@sh.itjust.works may I suggest pretending you are looking at it from the perspective of an asteroid 30 degrees “above Earth” and circling us. That would make it accurateish.

Everything is perspective.
