The aim of this lecture is to present on Full Moon. A full moon is the lunar phase that occurs when the Moon is completely illuminated as seen from the Earth. At full moon, we are seeing all of the moon’s day side. At this time, 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.
