The Earth's motion around a center of mass is due to the presence of the Moon. Technically, the Moon doesn't orbit the Earth, they both orbit the center of mass they share, which is about 4661 kilometers from the center of the Earth. In astronomy, the center of mass is also commonly referred to as the barycenter.

What is the earths center of gravity?

The Earth's center of gravity is located at its geometric center, which is also the center of mass where the gravitational pull of the entire planet can be considered to act. This point is constantly changing due to the distribution of mass within the Earth and its interactions with other celestial bodies in space.


Why gravity doesn't attract different objects arround us towards each other?

Because gravity pulls everything to the center of the Earth. We and objects around do not create gravity fields so they do not pull anything, instead they are subject to Earths gravity and that's why things don't float off into the air!

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.


What are effects of gravity?

Gravity causes older people to shrink. Answer Had to chuckle at the first answer though it is not true. Gravity is that force , said to originate from the center of the earth, which affects everything within its influence by attracting it to the earths center. Luckily we have a hard mantle beneath our feet that prevents this from happening.
