Center of gravity

In physics, the center of gravity of an object is a point at which the object's mass can be assumed, for many purposes, to be concentrated. For example, if you hang an object from a string, the object's center of gravity will be directly below the string.

The path of an object in orbit depends only on its center of gravity. Most astronomical objects are radially symmetric, causing both the center of gravity and the center of mass to coincide at the center of the sphere.

The center of gravity (CoG) of an object is the average location of its weight. In a uniform gravitational field, it coincides with the object's center of mass. (In modern Britain the spelling centre is standard. Both spellings originated in England; center is now standard in America.)
