What is a full moon?

A full moon is when the earth is at a point in its orbit where the moon is between the earth and the sun, and so the side of the earth that the moon is on (the “near side”) is illuminated fully by the sun, and the side of the earth that is in the dark is the “far side”.  The area illuminated by the sun is a circle, so if you’re looking up at the moon, it appears very large.  This is because the moon is in the same plane as the earth, so you’re seeing a huge circle of the surface of the moon.

How often does it happen?

In one month, the earth will go through all the positions where it is between the sun and the moon, so once every month the moon will be full.

Is it true that weird things happen during the full moon?
