The barycenter, aka, "center of mass", aka, "center of gravity" of the Earth-Moon system is located within the Earth. Due to Earth's rotation and the orbiting of the Moon, the Earth-Moon barycenter is always on the move. It is always about 1,000 miles beneath the surface of the Earth, or about 3,000 miles out from the center of the Earth. As you probably know, the barycenter lies on a straight line drawn through the centers of both the Earth and the Moon. This is one reason why some people do not agree that the Earth-Moon system is a binary- or double-planet system. They think that the barycenter should be outside both planets. However, every other satellite in the Solar System shares a barycenter with their planet that is at or very near the center of their planet. There is no other example where the barycenter lies so close to the surface, only 1/8 of Earth's diameter of about 8,000 miles. And there are other reasons to think of the Moon as a planet instead of a satellite. If you're interested, you'll find these reasons at the following website... http://paine_ellsworth.home.att.net/billbill.html#Selene Indelibly yours, Paine Ellsworth
What else can I help you with?
How does the earth-moon barycenter orbit the sun?
In an ellipse, as described by Kepler's laws. Though this is usually applied to the planet, it is more accurate to apply it to the barycenter of planet + moons.
Is the center of mass between Earth and the sun exactly half way between the two?
No, the center of mass between Earth and the sun is not exactly halfway between the two because the sun is much more massive than Earth. The center of mass is closer to the center of the sun, but it is not exactly at the halfway point.
What is the name given to the center of gravity of earth moon system?
The barycenter is the point between the Earth and the Moon where they balance each other's gravitational pull.
Why is the barycenter of the earth moon system located inside earth?
The barycenter of the Earth-Moon system is located inside the Earth because of the significant mass difference between the two bodies. The Earth is approximately 81 times more massive than the Moon, which causes the barycenter to be closer to the center of the Earth rather than in space. This point is located about 4,600 kilometers from the Earth's center, well within the Earth itself. As a result, the gravitational influence of the Earth dominates the system, keeping the barycenter inside its volume.
Why is the barycenter of the earth's moon system located inside earth?
The barycenter of the Earth-Moon system is located inside Earth because the Earth is significantly more massive than the Moon, with a mass about 81 times that of the Moon. The barycenter is the center of mass around which both bodies orbit, and since the Earth's mass dominates, this point is situated about 4,600 kilometers from the Earth's center, which is within the Earth's radius. This means that while both the Earth and Moon orbit around this barycenter, it remains inside the Earth due to the Earth's greater gravitational influence.
What are the different way the earth move?
The earth turns on its axis; it orbits around the earth-moon barycenter; it orbits around the sun.
How does the earth-moon barycenter orbit the sun?
In an ellipse, as described by Kepler's laws. Though this is usually applied to the planet, it is more accurate to apply it to the barycenter of planet + moons.
What are three different ways that the earth moves?
The earth turns on its axis; it orbits around the earth-moon barycenter; it orbits around the sun.
How certain is the barycenter of the solar system?
The "barycenter" of any system - for example, the Earth and the Moon - is the center of mass, which is also the center of the orbital motion within the system. For Pluto and its "moon" Charon, the "barycenter" is somewhere between the two objects, which are of (very roughly) similar size. In the Earth-Moon system, the "barycenter" is not the center of the Earth itself, but is still located within the Earth. If it were not, then the Moon wouldn't be a "moon" at all; it would be a co-orbiting planet. So technically, Charon isn't a moon of Pluto, but a co-planet. Because the Sun contains about 99.5% of the mass of the entire solar system, the barycenter of the solar system is very close to the center of the Sun. Not quite exactly; Jupiter's mass moves the barycenter of the system very slightly.
Is it likely that the sun will orbit the earth?
Technically, no object orbits the other; instead, they orbit their mutual "barycenter", which is a balance between the masses of the two objects. For example, the Earth and the Moon both orbit their "barycenter", which is still within the volume of the Earth. (That's why the Earth is the planet and the Moon is the satellite, instead of us being co-planets.) Because the Sun is SO massive and the planets so relatively puny, the barycenter of the Sun-Earth system is pretty much at the center of the Sun; the Sun itself wobbles an incredibly tiny amount. But that star-planet wobble is sometimes enough for us to detect it; that's how the first dozen or so extra-solar planets were discovered, because of the gravitational wobble caused by the planet!
Is the center of mass between Earth and the sun exactly half way between the two?
No, the center of mass between Earth and the sun is not exactly halfway between the two because the sun is much more massive than Earth. The center of mass is closer to the center of the sun, but it is not exactly at the halfway point.
Why is the Moon's gravity has greater effect on earth's ocean tides than the sun's gravity?
This is true because the moon is much closer to earth. Gravitational attraction is in inverse proportion to the square of the distance between two point masses like the sun and earth. Even though the sun is huge, it is also very far away. The earth and moon actually orbit each other; they orbit a common point called the barycenter. The barycenter is within the body of the earth, and it moves in such a way that it is always between the centers of the earth and moon.
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.
What is the name given to the center of gravity of earth moon system?
The barycenter is the point between the Earth and the Moon where they balance each other's gravitational pull.
Does the earth move around the sun the moon or mars?
The earth moves around the sun it is yearly orbit of the sun. The earth and the moon actually move around each other, since they both orbit what is called the 'barycenter', the center of gravity of the earth-moon system. The barycenter is beneath the earth's surface, and moves in such a way that it is always in line with the moon's center of gravity and the earth's. This gives earth a slight wobble in its yearly orbit of the sun. The earth does not move around Mars.
