-- The earth and moon both orbit their "common center of mass" ... the point
between them where the pivot of the see-saw would have to be in order for
them to balance each other.
-- Since the earth's mass is about 80 times as much as the moon's mass, that
point has to be 80 times farther from the center of the moon than it is from the
center of the earth.
-- The result is that their "common center of mass" is actually inside the earth.
So if you're watching the pair from the outside and you're not measuring too
closely, you'd swear that the moon is going around the earth, and you wouldn't
notice that the earth is also slightly wiggling.
-- By the way ... People often ask "Does the moon orbit the sun or the earth ?"
That "common center of mass" of the earth-moon pair is actually the thing that's
in orbit around the sun, while the earth and moon are both circling around it.

∙ 15y agoYes. It's moving away from Earth at a rate of about 4 cm (1.6 inches) per year. This movement is independent of the regular effect of the moon's elliptical orbit that causes the moon to get a little closer and then a little farther away from the earth each month. The moon is in fact moving very slowly farther and farther from earth.

∙ 15y agoYes. The furthest distance is known as apogee, and the closest distance (on its monthly journey around the earth) is perigee.
In addition, the moon is receding from the earth due to tidal friction, at a rate of about 0.85 inches per year.

edit: The amount of gravity that the earth pulls on the moon is almost exactly balanced out by the speed of the moon.

Do the Moon's phases go away when it is daytime on Earth?
No. The Moon's phases do not 'go away', they simply become less visible when sunlight outshines the Moon's reflection.
How far away is the Moon from Earth this month?
I want to know the exact date the moon is furthest away from the earth.
How much does the moon move away from earth each year?
The moon moves about 4cm away from the earth each year. This is because the moons orbit around the earth is tilted about 5 degrees. The moon is spiraling away from the earth and one day we might not have a moon.
Is the moon moving closer to the Earth or farther away?
The moon is moving further away by 1.5cm from the Earth every year.
What would happen if the moon slowly moved away from earth?
The moon does slowly move away from earth at an estimated two inches every year, it is a possibility that (if you believe in the apocalypse) the cause for the fall of Earth is the moon losing its orbit with earth and drifting away.
Do the Moon's phases go away when it is daytime on Earth?
No. The Moon's phases do not 'go away', they simply become less visible when sunlight outshines the Moon's reflection.
Which is near to the earth sun or moon?
The moon is much closer to the earth that the sun. The moon is about 239,000 miles away. The sun is about 93,000,000 miles away.
How long does it take to go to the moon by the speed of light?
At its average distance from the earth, the moon is 1.28 light seconds away.

How far away form the earth is the moon in km?
The moon is 384,400 kilometers away.
What is the earth length away from the moon?
The average distant from Earth to the Moon is about 238,874 miles
Where is the moon with respective to the earth in the solar system?
The moon orbits the earth. It is 238855 miles away from earth.
Which is the nearest the moon or the sun?
The Moon is closer at 384400 km (0.0026 AU) away from Earth while the Sun is 150000000 KM (1 AU) from Earth.
What is the phase of the moon that happens when the lighted half faces away from earth?
If the hemisphere that is 'lit' is facing away from the earth then it is a new moon
What would happen if the moon slowly moved away from earth?
The moon does slowly move away from earth at an estimated two inches every year, it is a possibility that (if you believe in the apocalypse) the cause for the fall of Earth is the moon losing its orbit with earth and drifting away.
