The Moon is Earth's only natural satellite. It is an average 240,000 miles away from earth and travels in an elliptical orbit. Being a proportionally large luminary, the moon is a quarter of the size of the planet earth (2,160 miles in diameter). Its surface is covered, with volcanos, mountains, valleys and craters giving the moon a rugged terrain in some ways similar to Earth's. However unlike Earth, it has no water or atmosphere, making it uninhabitable.

In astrology, the moon represents the emotional and maternal aspects of a personality. It's position in your chart affects the way you express your feelings and your instinct. It also controls your dreams, memory, childhood, your sensitivity towards others and your past.

In modern psychology, the moon represents our moods, instincts and subconscious. It controls moods and bodily cycles. Terms such as "moon madness" have been coined to express the excess energy some feel at the time of the full moon.
