What is the center of gravity in aviation?

The center of gravity is the balance point of the airplane—the location where it would balance if supported there. This position matters because it determines how weight acts with the aerodynamic forces about the longitudinal axis, directly affecting stability and controllability. If the CG is too far forward, the airplane becomes more thermodynamically stable but elevator control becomes heavier, making rotation and pitch control harder. If the CG is too far aft, the aircraft can become unstable and harder to control, with reduced stability and possible adverse stall behavior. That’s why the CG must stay within the approved forward and aft limits—so the airplane remains safe to fly with predictable handling. This point isn’t simply a nose-to-tail distance, nor is it the point where the main wheels touch the ground, nor the center of lift distribution. Those describe different concepts.
