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.
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.
The barycenter is the point between the Earth and the Moon where they balance each other's gravitational pull.
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.

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.
It takes approximately 27.3 days for the Earth to complete one full revolution around the Earth-Moon system barycenter. This is because the Moon's gravitational pull causes the Earth to wobble as it orbits the barycenter, resulting in the longer period compared to the Earth's rotation period.

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.
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.

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.
The barycenter of the Earth and Moon is the point around which they both orbit. It is significant because it helps determine the motion and stability of their orbital relationship. The barycenter is not at the center of the Earth, but rather closer to the Earth's surface due to the Moon's gravitational pull. This balance of gravitational forces keeps the Earth and Moon in a stable orbit around each other.

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).
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.

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.
