Moon is Earth’s only natural satellite. It is the fifth largest satellite in the Solar System.
The average distance from the Earth to the Moon is 384,403 km, about thirty times the diameter of the Earth. The Moon’s diameter is 3,474 km, a little more than a quarter of that of the Earth. Thus, the Moon’s surface area is less than a tenth that of the Earth (about a quarter the Earth’s land area, approximately as large as Russia, Canada, and the United States combined), and its volume is about 2 percent that of Earth.
The pull of gravity at its surface is about 17 percent of that at the Earth’s surface. The Moon is the only celestial body to which humans have traveled and upon which humans have performed a manned landing.
Gravity of the Moon distorts surface of the Earth, and pulls the ocean’s tides. Moon affects all living organisms on the deepest levels, and rules human’s unconscious, and our emotions.
