The Phases of the Moon

When one observes the phases of the moon he sees the moon's day and night, a shadow created from the sun illuminating half of the spherical moon at any one time.

The lunar phases vary cyclically according to the changing geometry of the Moon and Sun, which are constantly wobbling up and down and exchange altitudes as they rotate around the North Pole.

When the moon and sun are at the same altitude one half of the lunar surface is illuminated and pointing towards the sun, This is called the First Quarter Moon. When the observer looks up he will see a shadow cutting the moon in half. The boundary between the illuminated and unilluminated hemispheres is called the terminator.

When the moon is below the sun's altitude and near it, the moon is dark and a New Moon occurs.

When the moon is above the altitude of the sun and opposite from it, the moon is fully lit and a Full Moon occurs.

The time between two full moons, or between successive occurrences of the same phase, is about 29.53 days (29 days, 12 hours, 44 minutes) on average. This denotes the cycle of alternating altitudes.

Lunar Orientation
Q: Why does the orientation of the moon look the same to everyone one earth regardless of where they are?

A: It doesn't. The orientation varies depending on your location on earth. In FET this is explained by the different observers standing on either side of the moon. On one side it is right-side up, and on the other side it is upside down.

Imagine a green arrow suspended horizontally above your head pointing to the North. Standing 50 feet to the South of the arrow it is pointing "downwards" towards the Northern horizon. Standing 50 feet to the North of the arrow, looking back at it, it points "upwards" above your head to the North. The arrow flip-flops, pointing down or away from the horizon depending on which side you stand.

The lunar orientation varies depending on where you stand on a Round Earth as well. Here is the RET explanation for why the moon turns upside down when you stand on either side of it: http://web.archive.org/web/20070218184023/http://www.seed.slb.com/qa2/FAQView.cfm?ID=1137
