The Moon The Quarter Moons occur when the Sun and the Moon are 90º degrees apart in the sky as viewed from the Earth. The New and Full phases occur during times when the Earth, Moon and Sun are in a straight line. Figure 8 is a composite of the various phases and the location of the Moon in the sky. Remember, it takes about a week for the Moon to go from one major phase to the next, so that the view you see during one evening isn't too much different from the view you see the next night. You may have seen the Moon when it is close to the Full phase and it may appear to you to be Full for several days, while technically it is only Full at the time it is in a line with the Earth and the Sun. Also, the way that the Moon is illuminated gives us the view we see - when most of the lit surface is turned away from the Earth, we see only a small crescent; when most of

You can see how the Moon looks to you in the sky depending upon where it is located in its orbit about the Earth. Figure 8. The phases of the Moon shown at their locations relative to the position of the Earth and the Sun (off to the right). The phase of the Moon is determined by its location relative to the Earth and Sun. The right side of the Moon is the only part that is illuminated, since the Sun is off to the right. The phase that we see depends upon how much of that side of the Moon is visible from the Earth, which depends upon where the Moon is in its orbit about the Earth....
