Skylore assigns names for every full moon. Here in the Northern Hemisphere, the July full moon is called the Buck Moon, Thunder Moon or Hay Moon. In the Southern Hemisphere, where it’s winter now, this full moon is the Wolf Moon, Old Moon or Ice Moon.

A full moon is always opposite the sun. That’s why it looks full to us. At full moon, the moon and sun are on a line, with Earth in between. It’s as though Earth is the fulcrum of a seesaw, and the moon and sun are sitting on either end of the seesaw. So as the sun sets in the west, the full moon rises. When the sun is below our feet at midnight, the full moon is highest in the sky. When the sun rises again at dawn, the full moon is setting.

As the moon orbits Earth, it changes phase in an orderly way. Follow these links to understand the various phases of the moon.
