Because those are the eight points and shapes, during the constantly changing
appearance of the moon, to which we have given names. If you watch the edge
of the bright portion of the moon for a while through a small telescope, you'll see
that it's moving continuously, and so the actual apparent shape of the moon is
changing continuously ... literally minute to minute.
The Moons Revolution around earth is about 30 days. So if you divide that by 8 (because there are 8 phases) you would get about 3.75 days in between each phase. That is New, Cresent, First Quarter, Gibbous, Full, Gibbous, Third Quarter, Cresent and then once it gets back to New Moon again, its starts over again.
One Earth day is 24 hours, a lunar day is 28 days, 12 hours, 44 minutes longer than this. On average, a lunar day is 29 days, 12 hours, 44 minutes long, which is the time taken for the moon to go through all of the phases. It orbits the earth once every 27 days and 8 hours, but takes a little longer to complete lunar day due to the earths precession around the sun in that time.
the next lunar eclipse should be December 21,2010 between 7:30 and 8:30
