The phases of the moon refer to the shape of the illuminated portion of the moon, as seen by an observer on earth. The illuminated portion of the moon is the portion that is illuminated by the sun. The phases of the moon change as the moon orbits the earth, and depend upon the relative positions of the earth, moon, and sun.
The moon orbits around the earth with the same side always facing towards the earth. This type of orbit is called synchronous orbit. The moon's prominence in the sky and the ongoing phase cycle has, since ancient times, influenced culture, language, calendars, art, and mythology.
The distance of the moon from the earth, which is about thirty times the diameter of the earth, causes it to appear almost the same size as the sun. This allows it to cover the sun in total solar eclipses.
It is estimated that the moon formed almost 4.5 billion years ago, after the earth formed. It is currently believed that the moon formed from the debris left over by a giant impact between earth and a mars-sized body.
The moon is the only celestial body other than earth where humans have explored. The Soviet Union was the first country to send an unmanned spacecraft to the moon in 1959. The United States, with their Apollo program, was the only country to have sent manned missions to the moon, beginning in 1969, and ending in 1972.
