+ The distance From Earth is 363,301 kilometers (225,745 miles).
+ The radius of the moon is 1,738 kilometer (1,080 miles), the diameter is 3476 kilometers (2,160 miles).
+ Total weight: of the moon is 74 sextillion kilograms (81 Quintillion Tons).
+ The surface temperature at the equator during the day is 134oC (273o F), and at night is - 153o C (244o F)
+ Gravity at the surface of the moon is 1/6 that of the Earth.
+ The Orbital speed of the moon is 3680 km per hour (2,287 mph).
+ It would take 135 days to drive by car (@70 mph) to the moon
+ It takes several days of flight-time to get to the moon by rocket.
+ The age of the oldest rock collected is 4.5 Billion years old.
+ The rocks collected by Apollo weigh 382 kg (842 pounds).
+ The moon's widest craters are 225 km (140 miles) in diameter.
+ The moon's deepest craters are 4,500 meters (15,000 ft.)
+ The moon's highest mountains are 5,000 meters (16,000 ft)
+ From Earth, we always see the same side of the moon.
+ The lunar day (or the time from sunrise to sunrise) on the moon is approximately 708 hours
+ On July 20, 1969, Neil Armstrong became the first human being to set foot on the Moon.
+ The moon is actually moving away from earth at a rate of 1.5 inches per year.
+ The surface area of the moon is 37,932,000 square km (14,658,000 square miles) or 9.4 billion acres.
+ Only about 59 percent of the moon's surface is visible to us here on earth.
+ The moon is not round, but egg shaped with the large end pointed towards earth.
+ The earth rotates about 1000 mph. By comparison, the moon rotates about 10 mph.
+ If you weigh 120 pounds, you would weigh only 20 pounds on the moon.
+ The moon has no significant atmosphere or clouds.
+ Its surface is scarred from hundreds and thousands of meteors that have struck it over billions of years.
+ The Moon's surface layer is called regolith.
+ There are no active volcanoes on the moon.
+ "Moonquakes" are millions of times less powerful than earthquakes.
+ The Lunar Prospector spacecraft found evidence for water ice in the permanently shadowed areas of the lunar poles.
+ There are two high tides and two low tides every day on every beach on Earth, because of the moon's pull.
+ Only 12 people have ever walked on the surface of the moon.
+ People have not gone to the moon since 1972.
+ From 1972 to 2007 only four spacecraft orbited the moon, Clementine, Hiten, Lunar Prospector and Smart-1.
+ Some people believe that moonlight causes insanity. "Don't stare at the moon. You'll go crazy."
+ The word "lunatic" comes from when doctors thought that the insane were "moonstruck."
+ The ancient Chinese greeted solar eclipses by using noisemakers and by shooting arrows toward the heavens.
+ The Moon's orbit is inclined 5 degrees from the Earth's ecliptic.
+ The face of the Moon is marked by regions, called mare, Latin for "sea". A name given by Galileo who thought the dark featureless areas were bodies of water. We now know them to be basalt (a type of lava) filled impact basins.
+ The Moon's magnetic field is 100 to 1000 times weaker than the Earth's
+ The sidereal month is the average period of revolution of the moon around the earth in reference to a fixed star, equal to 27 days, 7 hours, 43 minutes in units of mean solar time.
+ The cause of moon phases is that from the Earth we see the part of the Moon that is illuminated by the Sun from different angles as the Moon traverses its orbit. So the appearance depends on the position of the Moon with respect to the Sun (as seen from the Earth). Because the Earth orbits the Sun, it takes the Moon extra time (after completing a sidereal month, i.e. a full circle) to catch up and return to the same position with respect to the Sun. This longer period is called the synodic month
