Why do the moon go around the earth instead of the earth going around the moon?

-- 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 orbiting it.

∙ 12y agowell first of all, the proper way to ask this question is "why does the Earth revolve/rotate around the Moon instead of the Moon revolving around Earth? " my answer [which is in my opinion ]
the answer is that the Earth's gravitational pull makes the Earth orbit around the moon. but if you needed a simple answer that answer would be that God made it that way when he created the universe. i <3 earth < Peace dudes!>

What is it called the path the moon follows around the earth?
The path that the moon follows around the Earth is called an orbit. The planets going around the sun is called revolution. The moon goes around the Earth in a month.
Does the moon orbit the sun or the moon?
Both. because the moon goes around the earth while the earth is going around the sun. And that's how it orbits both.
How many years does it take for the moon to go around the sun?
The moon goes around the earth. The earth goes around the sun in a year. So, for purposes of astronomy, the earth and moon are one unit going around the sun. Therefore the moon goes around the sun in one year.
Why does earth pull the moon instead of the other way around?
The moon does pull the earth. All bodies affect others according to their mass and distance
Does the moon move around the sun the earth?
The moon revolves around the Earth and the Earth revolves around the sun. The moon does not revolve around the sun.
Why did ancient astronomers assume the sun and moon orbit the earth?
Well they looked at the sky and figured they could always see them both and that they were just going around the earth. Not that the moon was going around us but we were going around the moon.
How would the tides on earth be diffrent if the moon revolved around earth in 15 day instead of 30day?
the moon's gravitional pull on earth decreases with the moon distance from earth
What is it called the path the moon follows around the earth?
The path that the moon follows around the Earth is called an orbit. The planets going around the sun is called revolution. The moon goes around the Earth in a month.
Does the moon orbit the sun or the moon?
Both. because the moon goes around the earth while the earth is going around the sun. And that's how it orbits both.
What is the reason for moon's circular motion around the earth?
Earth exerts a pull on the moon, which keeps it orbiting the Earth. Since the Earth is so big compared to the moon, it pulls the moon toward it. In a sense, the moon is falling towards the Earth, but since the moon is also moving forwards, it ends up going around and around the Earth.
Why is the moon phase cycle longer than the Moon's revolution around earth?
The Moon takes 27.3 days to go around the Earth once, but the time from new moon to new moon is 29.5 days. This is because while the Moon is going around the Earth, the Earth keeps moving going around the Sun. By the time the Moon has made exactly one orbit, the Earth has moved another 27.3 days along in its orbit, and it takes the Moon another 2.2 days to get back into the same relative arrangement of Sun-Moon-Earth.
Is it possible for the moon to pull the earth and make the earth orbit around it instead?
No, the Earth has more mass and therefore has more gravity, so unless over 3/4 of the Earth was blown up, it's not going to happen.
How many years does it take for the moon to go around the sun?
The moon goes around the earth. The earth goes around the sun in a year. So, for purposes of astronomy, the earth and moon are one unit going around the sun. Therefore the moon goes around the sun in one year.
Why it takes longer time for a new moon to appear than it takes the moon to go around the earth?
this is because going around the earth is a constant process... and new moon this is because when the
Why does earth pull the moon instead of the other way around?
The moon does pull the earth. All bodies affect others according to their mass and distance
Is the distance of the moon from the earth the same as it complete the revolution?
The distance between Earth and Moon changes. Like any object going in an orbit around another object, the Moon moves around Earth in an ellipse, not in an exact circle.
What the moon does around the earth?
The moon revolves around Earth.
