Does a comet rotate around the sun or earth?
Fasten your seat-belt: The Earth and Moon both orbit their common center of mass ... the place where the pivot would have to be if the Earth and Moon were on opposite ends of a see-saw. Since the Earth has roughly 80 times as much mass as the Moon has, the pivot has to be 80 times as far from the center of the Moon as it is from the center of the Earth, which means that the point they're both orbiting is actually inside the Earth. That's why it looks like the Moon is orbiting the Earth ... the Moon is making this tremendous trip around the common center and the Earth is barely wiggling. You heard it here first.
How much moons are there around earth?
The earth only has one moon
What can determine moon phase?
The position of the earth and moon on their orbit around the sun, determines how much and what area of the moon is lit by sunlight. The moon's phases are what we can view from the earth.
What what is the shape of the moon's orbit around Earth?
The orbit of the Moon around the Earth is elliptical. An ellipse is a flattened circle, much like an oval. The Moon takes just under a month to revolve around the Earth. Looking down on the Earth above the North Pole, the Moon revolves counterclockwise around the Earth, which is the same direction that the Earth rotates on its axis.An ellipse. Very close to a circle though.Unlike many other moons, the Earth's moon follows an elliptical orbit.
Is it just a coincidence that the time for the moon to revolve around the earth is the same as the time for the moon to rotate on its axis or is there some scientific reason for these to be the same?
No, that's no coincidence. Many, perhaps most, moons in the Solar System have the same rotation pattern. The Moon must have gradually slowed down, due to tidal forces, until it always shows Earth the same side. (If it rotates slower than its revolution, tidal forces would speed its rotation up.) Similarly, Earth is rotating slower and slower, until one day in the distant future, it will always show the Moon the same side. However, since Earth has much more mass than the Moon, slowing it down takes longer.
What is the alignment of the sunearthand moon?
All three rotate around a common center of gravity. Since the sun is so big, the common center is within it, so we can say that the Earth - Moon pair rotates around the sun. Since the Earth is so much larger than the moon, the same is true and you can say that the moon rotates around the Earth. But note that the moon never goes "backward", both Earth and the Moon follow a wavy path around the sun.
Does the moon orbit the earth or the earth orbit the moon?
The Moon orbits the Earth, but technically, the Moon and Earth orbit each other, around their center of mass. Due to the Moon's size, the Moon-Earth system is sometimes called a "binary planet" system.A little bit of both. Earth is much more massive than the Moon so the Moon mostly goes around Earth, but the Moon does still tug Earth around somewhat.The Moon helps with the Earth's tides.In more scientific language, the Earth and Moon both rotate around their common centre of mass, called the barycentre.This is actually inside the planet Earth. So, although it's not strictly correct, it'spretty accurate to say that the Moon orbits the Earth.
Why the moon orbits around earth not the sun?
The Moon orbits around the Earth because it is under the gravitational influence of Earth. This gravitational force between the Earth and the Moon keeps the Moon in orbit around the Earth. The Sun's gravitational force is much stronger, but the Moon's orbit around the Earth is stable due to the balance between these gravitational forces.
How much does earth rotate in six hours?
in average speed it has to be around 648000km
Why does a person n earth always sees the same side of the moon?
The Moon rotates in such a way that it always shows us the same side - it takes 27 days to go once around the Earth, and 27 days to rotate around its own axis. The reason for this is that the Moon's rotation, which was probably much faster initially, slowed down, through tidal forces from the Earth - just as the Earth's rotation is currently slowing down, due to tidal forces from the Moon. Many moons in the Solar System have this bound rotation - they rotate once every time they go around their planet.
Why the moon changes through a cycle each month?
The moon does not change (much). What an observer on Earth sees changes as the Moon orbits the Earth and the Earth/Moon system orbits the Sun much more slowly is the illuminated portion of the moon growing (covering more and more of the visible portion of the Moon) and when the Moon is full, the Sun Earth and Moon are more or less in line (if they were exactly in line it would be a lunar eclipse - which does happen a few times each year). Then as the Moon continues to rotate around the Earth, night after night, less and less of the illuminated portion is visible to the observer on Earth.

Does the sun move in an elliptical orbit or does the moon?
Both the Earth and the Moon move in the universe. Earth and Moon actually orbit their common center of mass. Together, the Earth and the Moon orbit the Sun, which itself is moving in the universe.
Does the moon revolve around the earth much slower then it rotates?
The moon rotates around the earth at the same rate that it rotates around it's own axis. This means that from earth it is only possible to see one side of the moon. That is why the moon rover expeditions were so intriguing to scientists.
How are the earth and the moon opposite?
The Earth and the Moon are opposite in terms of size, with Earth being much larger than the Moon. Additionally, they have opposite positions in the solar system - the Moon orbits around the Earth, while the Earth orbits around the Sun.
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.
