Full Moon – What is a Full Moon?


What is a Full Moon? A full moon takes place when the moon and the Earth are located on opposite sides of the Sun. At this time, the moon, earth, and sun are aligned in a straight line. A full moon is a lunar phase, in which the illuminated side of the moon faces the Earth and humans see the lighted side of the moon. Lunar eclipses are only possible during a phase of the full moon. When the geocentric longitudes of the moon and the sun are at a variance of precisely 180 degrees, a full moon occurs. An observer on Earth would see an almost completely illuminated and perfectly round moon. It is only when the moon is full that the opposing side, which is not visible to an observer on Earth, is entirely unlit­. Observers are faced with the illusion that the moon is perfectly round, however the moon is actually more of an egg shaped and the pointed end is facing the earth. A full moon is a beautiful phenomenon which possesses the extreme glowing light and size in the sky to draw the attention of any viewer on Earth.
