Latitude and longitude are also used on the moon by the astrogeology department of the United States Geological Survey in Flagstaff, Arizona, which maps extraterrestrial bodies.
Like the earth, the moon has an axis of rotation and an equator, so latitude is indicated in degrees of latitude north or south of that equator, just as it is on earth.
Because the sphere of the moon is smaller, each degree represents a smaller distance.
Another difference in moon maps is the starting point for lunar meridians of longitude.
A spot in one crater has been specified as the equivalent of Greenwich, England. It is the point through which the line marking zero degrees of longitude runs.
The crater, called Mosting A, lies near the center of the disk of the full moon as we see it.
