That's the center of mass of two or more objects that orbit each other.
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.
The barycenter is the center of mass of two or more bodies that are orbiting around each other, such as a planet and its moon or a star and its planets. It is the point where the weighted positions of the bodies balance out, and it often lies within or outside the physical bodies depending on their relative sizes. For example, in the Earth-Moon system, the barycenter is located beneath the Earth's surface due to its larger mass. Understanding barycenters is crucial in fields like astronomy and orbital mechanics.
When binary stars have similar masses, the barycenter is located at the midpoint between the two stars. This means that the center of mass of the system lies halfway between the two stars, with each star orbiting around this point in a stable manner.
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 common center of gravity, or barycenter, of the Earth and Moon is located inside the Earth, about 4,600 kilometers (approximately 2,900 miles) from the Earth's center. This point lies beneath the Earth's surface because the Earth is significantly more massive than the Moon. The barycenter moves as the Moon orbits the Earth, but it remains within Earth's volume due to the mass difference.
The barycenter is the point between the Earth and the Moon where they balance each other's gravitational pull.
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.
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 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.
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.

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 moon is a celestial body. that orbits the earth. though it does not have its own barycenter.
Moons orbit planets Or rather moons and planets orbit their barycenter.
In the Star Wars mythos, there are two planets in the Corellian System named Talus and Tralus. They both orbit around the same barycenter, therefore they are "sister planets." There is a space station at the barycenter called Centerpoint Station, which played a major role in the Corellian Trilogy of books.
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).
