The center of mass of Earth is located at a point close to its geometric center but shifted slightly towards the side where the heavier mass concentration is. This point is crucial for various calculations in physics and astronomy.
Venus is closest to the Earths size and mass - often referred to as Earths sister or twin planet. Venus' Mass is around 82% of Earths, while its diameter is a little smaller than Earths at around 95% of Earths diameter.
Saturn has a mass roughly equal to 95 times the mass of Earth, so 318 Earths would be about 3.35 times the mass of Saturn.

The distance from the center of mass to Earth, times the mass of the Earth, must be equal to the distance of the center of mass to the Moon, times the mass of the Moon. (For more than 2 objects, the calculation is somewhat more complicated - reading about "center of mass" can give you an idea.)The distance from the center of mass to Earth, times the mass of the Earth, must be equal to the distance of the center of mass to the Moon, times the mass of the Moon.

Its weight will change depending on the position, but its mass will hardly change.
One kilogram. Mass is invariant.The weight at that point is zero. But the mass doesn't change.
The Earth's mass, and how far you are from the center of the Earth.

The center of mass of Earth's atmosphere is located close to Earth's geometric center, but it can be slightly influenced by atmospheric circulation patterns and mass distribution. Overall, it is within the region of Earth's core, beneath the crust and atmosphere.
Assuming that the atmosphere is distributed evenly all over the Earth, its center of mass is of course at the Earth's center. If for any reason there is more atmosphere on one side than on the other, the center of mass would be slightly away from Earth's center.
Every speck of mass throughout any solid body "has gravity", and attracts every other speck of mass. But when you're outside of the solid body, the gravitational effect of all those specks of mass is exactly as if all of its mass were located at its "center of mass" or "center of gravity". For a homogeneous spherical object, that point is the center of the sphere.
You would have to double your distance from the center of the earth, or about 4,000 miles off the surface.
The earth's center of gravity is the center of the earth, or the center of the mass with the mass being the earth. The earth spins as it moves through space on account of sun's gravitational forces and because there is nothing in space to get in the way or stop the earth from rotating.
Mercury's mass = 0.055 x Earths, Volume = 0.056 x Earths Mars' mass = 0.1075 x Earths, Volume = 0.151 x Earths Venus' mass = 0.815 x Earths, Volume = 0.857 x Earths (Earth) mass = 1 x Earths, Volume = 1 x Earths Uranus' mass = 14.536 x Earths, Volume = 63.086 x Earths Neptune's mass = 17.147 x Earths, Volume = 57.74 x Earths Saturn's mass = 95.152 x Earths, Volume = 763.59 x Earths Jupiter's mass = 317.8 x Earths, Volume = 1321.3 x Earths
The core is 33% of the Earths mass
The weight of an object is its mass times the acceleration of gravity. The acceleration of gravity at the center of the Earth is zero. A 1 kg mass at the center of the Earth still has a mass of 1 kg, but the force of attraction between the 1kg mass and all the other mass around it will add up to zero.
