The dark side of the moon never faces the sun origin










On the equator, when the Moon rises in the east, its N - S axis appears horizontal and Mare Foecunditatis is on top.

  • In mid northern latitudes (North America, Europe, Asia) the Moon rises in the east with its northeastern limb up (Mare Crisium), it reaches its highest point in the south with its north on top, and sets in the west with its northwestern limb (Mare Imbrium) on top.
  • On the north pole, if the Moon is visible, it stands low above the horizon with its north pole up.
  • In the following description a few typical cases will be considered. The Moon's actual orientation in Earth's sky or on the horizon depends on the viewers geographic latitude on Earth. When specifying coordinates on the Moon it should therefore always be mentioned whether geographic (or rather selenographic) coordinates are used or astronomical coordinates. But when the Moon is seen from Earth, then the east–west direction is reversed. West and east on the Moon are where they would be expected, when standing on the Moon. Astronomers traditionally turn the map to have south on top to correspond with the northern-hemisphere view in astronomical telescopes, which typically show the image upside down. The image of the Moon here is drawn as is normally shown on maps, that is with north on top and west to the left.
