Explanation of the Phases

Did you know that the phases of the Moon change as it orbits the Earth? The Sun is reflected on the surface of the Moon. The position of the Moon changes how much of the Moon we can see from Earth.

The first phase of the Moon is called a “New Moon”. This is where we can’t see any of the moon lit up by the sun. As the Moon orbits the earth, more and more of it is lit up by the sun and visible to us on Earth. A “Full Moon” happens when the Earth is located between the Sun and Moon. This is when the entire side of the Moon that is visible is lit up by the sun. As the Moon continues around Earth, we are able to see less and less of it until it becomes a “New Moon” again. The Moon goes through one full cycle each month. It takes 29.5 days to complete a cycle.
