What is the name given to the center of gravity of earth moon system?
The barycenter.
When is the gravitational pull of earth canceled by the moon's gravity?
The Moon does not just go around the Earth. In reality, the two objects orbit about a common gravitational midpoint, called a barycenter. The mass of each object and the distance between them dictates that this barycenter is inside Earth, about three-fourths of the way out from the center.
What is the barycenter of the sun and the Earth?
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.

Is the center of mass between Earth and the sun exactly half way between the two?
Yes, the center of mass for the earth-sun orbit lies inside the sun. This is the barycenter, by the way. And because the sun is so massive relative to earth, the barycenter of earth's orbit about our local star is not that far from the center of the sun and is actually inside of it.
How fast does the center of the earth rotate around the barycenter of the moon and the earth?
Simple answer . . . once each 27.32 days.More ambitious answer:The Earth-moon barycenter is about 1,710 km below the Earth's surface.That corresponds to 4,660 km from the Earth's center. So the Earth'sorbital speed around the barycenter is about ...4,660 km/27.32 days = 170.57 km/day = 4.41 miles per hour.
When two objects of unequal mass orbit where is the center of the mass?
The barycenter. The barycenter of the Earth - Moon system is inside the Earth about 2000 kilometers beneath the surface. The Barycenter of the Charon - Pluto system is in space between those celestial bodies.
Why cant earth called the natural satellite of moon?
The Earth doesn't orbit the Moon, and the Moon doesn't orbit the Earth; instead, both of them orbit their common center of mass, the "barycenter". The barycenter of the Earth-Moon system is INSIDE the Earth - so the Moon is a satellite of the Earth, not the other way around. If the barycenter of the Earth-Moon system were outside of the Earth, in space between them, then technically they would be "co-planets", not a planet and a moon.
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.

Can you describe the planetary system the moon is in?
Here are two bodies which are circling each other in space - a near perfect model of the gravitational attraction that one body has on another body. It is not just the moon that is revolving about the earth but that the moon has enough mass to cause the earth, in turn, to move in a circular orbit. It turns out that the two bodies orbit about a common center of gravity which is referred to as the barycenter . It can be shown that the distance of the center of each body from the barycenter is inversely proportional to their masses. In the moon/earth system this locates the barycenter about 2,900 miles from the center of the earth (the radius being about 3,960 miles). The moon is about 236,000 miles in the opposite direction from the barycenter (dividing 2,900 by 236,000 shows the earth to have 81 times the mass of the moon).
What does the moon do to create a tide?
It's all about gravity. The moon and earth each orbit around the 'barycenter', the center of gravity of the earth-moon system. this point is within the body of earth itself.
Is the center of mass between Earth and the sun exactly half way between the two?
Yes, the center of mass for the earth-sun orbit lies inside the sun. This is the barycenter, by the way. And because the sun is so massive relative to earth, the barycenter of earth's orbit about our local star is not that far from the center of the sun and is actually inside of it.
What does moon orbit and how long does it take?
The Moon orbits the common barycenter of the Earth and Moon (a point inside the Earth, so saying "the Moon orbits the Earth" isn't entirely wrong). It takes about 27 days 8 hours to do this.

What combines to keep Earth in orbit around the sun and the moon in orbit around Earth?
It's their mutual gravities, and technically, BOTH the Earth and the Moon are orbiting around the "barycenter" of the Earth-Moon System. Since the Earth is so much more massive than the Moon (81 times), the barycenter is actually inside the Earth, but not at its very center. Comment: I think this question isn't just about gravity. I think it's about the idea that a planet or moon has inertia. It would have motion in a straight line if it were not in a gravitational field. The combination of the inertia of the body with gravitational forces is what keeps the body in orbit.
