The moon is the only natural satellite orbiting Earth and the Earth's closest neighbor in space. This cold, rocky body is about 384,403 kilometers (238, 857 miles) away. This distance is similar to going around the earth 10 times.
The moon is 3476 kilometers (2,160 miles) in diameter. It is 1/4 the size of the earth. It is about 400 times smaller than the sun and 400 times closer. For this reason the sun and moon appear to be the exact same size.
The moon is very old!!! Scientists believe that about 4.5 billion years ago a Mars-sized body hit Earth and the resulting debris (from both Earth and the impacting body) accumulated to form the Moon. Scientists know this because they studied the lunar rocks that were collected by astronauts who went to the moon. The moon and the earth are made of the same material.
The daily maximum temperature is 250° F (hot enough to boil water). At night the temperature can reach -250° F.
The Moon has no atmosphere so the lunar sky is black. You need atmosphere to make the sky blue. Astronauts must carry their own air for breathing when they visit the moon.
The surface of the moon is covered in craters or holes that have been created by space rocks or meteors that hit the soil. The lack of atmosphere there allows the rocks to crash into the surface. An atmosphere would protect - just as it does here on the earth.
Ice exists in some deep craters near the Moon's south pole which are permanently shaded. This was confirmed by Lunar Prospector. There is probably ice at the north pole as well.
Weightless // If you weigh 60 pounds on earth, you would weigh 10 pounds on the moon because gravity is 1/6th as strong on the moon.
The same side of the moon always faces Earth which means that when we look up into the sky we can only see one side.
The moon has no light of its own. It shines because sunlight is reflected from its surface.
What is "moonrise?" The Earth rotates once a day on its axis causing the phenomena of the rising and setting of the sun and moon. They seem to appear in the sky at the horizon to the East, then to cross the sky and disappear at the horizon to the West. Photo
Phases of the Moon
The moon orbits, or revolves, around the Earth about once every 27 days, 7 hours, 43 minutes. This movement causes the moon to cycle through a series of phases: New, New Crescent, First Quarter, Waxing Gibbous, Full, Waning Gibbous, Last Quarter, Old Crescent and back to New again.
Sometimes the moon passes through some portion of the earth's shadow and the Earth blocks part or all of the sun's rays from reaching the moon. This is called a lunar eclipse and can only occur at Full Moon. Now you are ready to learn about a Lunar Eclipse from NASA. A schedule of upcoming eclipses can be found on NASA's website.
Earth rising over the lunar surface Almost three hundred sixty years after the Italian astronomer Galileo Galilei made his first observation of the Moon with a telescope in 1610, the Apollo 11 mission made the first landing on the Moon and returned samples in 1969.
Here's a BBC Documentary on the moon, which focuses on the importance of the moon to Earth's Climate, overall balance and Life. It also roposes to think of the moon as a Possible Spacial Station for missions to explore other planets or who knows? Maybe even galaxies. On a side note, underlines the fact that Moon's surface and conditions are ideal for Solar farms. I strongly recommend you to have a watch at it.
