They were originally called "maria" ("seas") because astronomers believed they were bodies of water. Banting is flanked by two U.S. lunar landing sites – those of Apollo 15 and 17 – which lie several hundred miles on either side of the crater. Mare Serenitatis is frequently perceived to be the eastern eye of the Man in the Moon. The Man in the Moon is on the near side of the
