Diagram explaining the moon phases

This diagram shows the relative positions of the Sun, the Moon and earth and explains how the different moon phases appear.

The visible part of the moon is the part of the moon's surface that gets hit by the sunlight. The rest of the moon disc is almost invisible.

The moon phases are not caused by the shadow of the earth on to the moon. It is the moon's own shadow at the part of its surface that is not hit by the sunlight.

In other words, the visible "sunny" part is made of the places where there is "day" on the moon and the shadow part is where there is "night".
