One tangible characteristic is that, if an object's center of gravity, projected downward, is inside the base where the object touches the ground, the object won't fall over.Another one is that, the higher the center of gravity of an object, the easier it is to push such an object over. For example, this may be relevant for cars on a road.
If you mean what is gravity then it's the characteristic of space that causes a pair of forces between you and center of a planet, for example earth. this is what causes how much you weigh, which is also why you weigh less on the moon.

It is always different depending on the object. For example a female humans' center of gravity is in the hip. as a male humans' center of gravity is in the chest. But once you have found the center of gravity in an object the center of gravity should be the same in every object like it.
The center of mass and center of gravity serve two separate purposes. As an individual, your center of gravity and center of mass remains the same. The earth has a center of mass. The moon has a center of mass. The moon does not orbit the earth. They orbit their center of gravity. Their center if gravity is always changing. It is not a fixed point. When an airplane takes off, its center of gravity is one place. As it burns fuel, its center of gravity changes. It might be necessary to change its attitude, which today is done automatically by computers. The computers are checked at the end of the flight by human beings.
No, objects cannot have more than one center of gravity. The center of gravity of an object can however change.

The center of gravity is an average of the location of the points of gravity. If you had a flying ring like a Frisbee but without the center, the center of the gravity would be in the hole.

the center gravity
That all depends on the shape of the object and how its mass is distributed. The center of gravity of a solid sphere is at the center of the solid sphere. The center of gravity of a solid cube is at the center of the solid cube. The Earth's center of gravity is at the center of the Earth, and there's certainly plenty of mass there. But the center of gravity of a ring is at the center of the ring ... an open space where the finger goes.

Since the atmosphere is more or less symmetric, its center of mass (center of gravity) gravity must be quite close to Earth's center.
Earths gravity acts on everything from its center of gravity to everything else's center of gravity.
