When Neil Armstrong took that first historical step and said "That's one small step for man, one giant leap for mankind" it would not have occurred to anyone that the step he took in the dust of the moon was there to stay. It will be there for millions of years because there is no wind on the moon. That is, assuming the downdraft from the Command Module upon takeoff back into space didn't destroy the print. Buzz Aldrin reportedly saw the American flag, much further away, blow over during launch. Nevertheless, any footprints made by the famous astronauts undisturbed by takeoff are, in fact, there to stay.
The surface area of the moon is 14,658,000 square miles or 9.4 billion acres
Only 59% of the moon's surface is visible from earth.
The moon rotates at 10 miles per hour compared to the earth's rotation of 1000 miles per hour.
When a month has two full moons, the second full moon is called a blue moon. Another definition of a blue moon is the third full moon in any season (quarter of year) containing 4 total full moons.
From Earth, we always see the same side of the moon; the other side is always hidden.
The dark spots we see on the moon that create the image of the man in the moon are actually craters filled with basalt, which is a very dense material.
The moon is the only extraterrestrial body that has ever been visited by humans. It is also the only body that has had samples taken from it.
The first space craft to send back pictures from the moon was Luna 3 (built by the Soviet Union) in October 1959.
The moon has no global magnetic field.
The moon is about 1/4 the size of the Earth
