2 The Phases of the Moon

3 Moon - Earth Relationship The revolution of the Moon around the Earth makes the Moon appear as if it is changing shape in the sky. These changes are called “phases” of the Moon. The Moon goes through 8 different phases in a period of 29.5 days.

4 The cause of these phases is the relative positions of the Sun, Earth, and Moon. Notice that no matter what phase the Moon is in, HALF of it is ALWAYS lit by the Sun. (Which half is always lit? The half that is facing the Sun.). Click Here

5 A View from Space

6 Same View from Earth

7 The reason that we do not always see a Moon which is half lit is because of our position relative to the Moon and the Sun. As the Moon moves in its orbit, different portions of it appear (to us!) to be lit up as we look at it from Earth. This is why we see lunar phases.

10 8 Lunar Phases from Space New Moon Waxing Crescent First Quarter Waxing Gibbous Full Moon Waning Gibbous Second Quarter Waning Crescent

11 8 Phases Viewed from Earth New Moon The lighted side of the Moon faces away from the Earth. All we see is dark! Click here to View from Space

12 8 Phases Viewed from Earth Waxing Crescent This moon is seen right after noon moon. Waxing = growing The crescent will continue to grow larger and larger every day! Click here to View from Space

13 8 Phases Viewed from Earth First Quarter The right half of the Moon appears lighted and the left side of the Moon appears dark. Click here to View from Space

14 8 Phases Viewed from Earth Waxing Gibbous This Moon can be seen after the First Quarter Moon, but before the Full Moon. The amount of the Moon that we can see will grow larger and larger every day. Waxing = growing Click here to View from Space

15 8 Phases Viewed from Earth Full Moon The lighted side of the Moon faces the Earth. The Moon that we see is very bright from the sunlight reflecting off it. Click here to View from Space

16 8 Phases Viewed from Earth Waning Gibbous This Moon can be seen after the Full Moon, but before the Last Quarter Moon. The amount of the Moon that we can see will grow smaller and smaller every day. Waning = grow smaller Click here to View from Space

17 8 Phases Viewed from Earth Third Quarter The left half of the Moon appears lighted, and the right side of the Moon appears dark. the part of the Moon that appears lighted gets smaller and smaller every day. It will continue to shrink until the New Moon, when the cycle starts all over again. Click here to View from Space

18 8 Phases Viewed from Earth Waning Crescent This Moon can be seen after the Last Quarter Moon and before the New Moon. The crescent will grow smaller and smaller every day, until the Moon looks like the New Moon. Waning = grow smaller Click here to View from Space

19 Phases of the Moon Now that we know all the Phases of the Moon click on the picture below to watch an animation of our Moon’s cycle.

20 MOON Calendar Click on the image below to see a MOON Calendar. You can see the phases of the moon for each day of any month!
