Alright, listen up! The barycenter of the Earth and Moon is the point around which they both orbit each other due to their gravitational pull. Technically, it's not at the center of the Earth because the Moon is tugging on our dear planet too. It's like a cosmic dance where both partners are swinging around a point somewhere between them.
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.
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.
Ganymede's orbital period around Jupiter is 7.154 Earth days.
The orbital period of Mars is 687 Earth days, or 1.88 Earth years. That is about 668 sols (Martian days).
The center of mass of the Earth-Moon system, also known as the barycenter, is the point around which the two bodies orbit each other. This point is located approximately 4,600 kilometers from the center of the Earth, which is inside the Earth itself, given that the Earth has a much larger mass than the Moon. The barycenter moves in response to the gravitational interactions between the Earth and Moon, but it remains relatively close to the Earth's center due to the significant mass difference.
Earth's orbital and relationship and gravitational relationship with Sun and 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 is the point between the Earth and the Moon where they balance each other's gravitational pull.
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.
It is within the body of the earth itself, because the mass of earth is so much greater than the mass of the moon. It is called the "Barycenter" or "Barycentre". It is a moving point, because of the orbital and rotational movements of the two bodies.
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.
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.
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 earth turns on its axis; it orbits around the earth-moon barycenter; it orbits around the sun.
