The moon is Earth’s only natural satellite. http://en.wikipedia.org/wiki/Moon
The gravitational attraction generated by the rotation of the Moon and Earth around a common point is largely responsible for the tides on Earth. http://www2.jpl.nasa.gov/galileo/images/earthmo2.gif
The Moon is the only celestial body to which humans have traveled and upon which humans have landed. http://nssdc.gsfc.nasa.gov/imgcat/thumbnail_pages/moon_thumbnails.html
The Moon is in synchronous rotation, meaning that it keeps nearly the same face turned towards the Earth at all times. The far side of the Moon The near side of the Moon http://en.wikipedia.org/wiki/Moon
The side of the Moon that faces Earth is called the near side, and the opposite side is the far side. The far side should not be confused with the dark side, which is the hemisphere that is not being illuminated by the Sun at a given moment. First images of the far side of the Moon taken from Luna 3 http://en.wikipedia.org/wiki/Moon
The phases of the moon are caused by the relative positions of the earth, sun, and moon. The moon goes around the earth, on average, in 27 days 7hours 43 minutes. http://www.google.com/search?sourceid=navclient&aq=t&ie=UTF-8&rls=DIUS,DIUS:2006-22,DIUS:en&q=phases+of+moon

The sun always illuminates the half of the moon facing the sun (except during lunar eclipses, when the moon passes thru the earth’s shadow). When the sun and moon are on opposite sides of the earth, the moon appears “full” to us, a bright, round disk. http://spaceplace.nasa.gov/en/educators/images/moon/Moon_phases_all_L.jpg
When the moon is between the earth and the sun, it appears dark, a “new” moon. New Moon - The Moon's unilluminated side is facing the Earth. The Moon is not visible (except during a solar eclipse). http://www.k111.k12.il.us/KING/phases_of_the_moon.htm
Waxing Crescent - The Moon appears to be partly but less than one-half illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is increasing. http://www.k111.k12.il.us/KING/phases_of_the_moon.htm
First Quarter - One-half of the Moon appears to be illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is increasing. http://www.k111.k12.il.us/KING/phases_of_the_moon.htm
Waxing Gibbous - The Moon appears to be more than one-half but not fully illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is increasing. http://www.k111.k12.il.us/KING/phases_of_the_moon.htm
Full Moon - The Moon's illuminated side is facing the Earth. The Moon appears to be completely illuminated by direct sunlight. http://www.k111.k12.il.us/KING/phases_of_the_moon.htm
Waning Gibbous - The Moon appears to be more than one-half but not fully illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is decreasing. http://www.k111.k12.il.us/KING/phases_of_the_moon.htm
Last Quarter - One-half of the Moon appears to be illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is decreasing. http://www.k111.k12.il.us/KING/phases_of_the_moon.htm
Waning Crescent - The Moon appears to be partly but less than one-half illuminated by direct sunlight. The fraction of the Moon's disk that is illuminated is decreasing. http://www.k111.k12.il.us/KING/phases_of_the_moon.htm
Eclipses can occur only when the Sun, Earth, and Moon are all in a straight line. Because the Moon’s orbit around the Earth is inclined by about 5 degrees with respect to the orbit of the Earth around the Sun, eclipses do not occur at every full and new moon. http://en.wikipedia.org/wiki/Lunar_eclipse
Solar eclipses can occur near a new moon, when the Moon is between the Sun and Earth. http://en.wikipedia.org/wiki/Solar_eclipse
Lunar eclipses can occur near a full moon, when the Earth is between the Sun and Moon. http://en.wikipedia.org/wiki/Lunar_eclipse
