Can we apply Earnshaw theorem in circular/elliptical/hyperbolic orbits? I was wondering how did the moon stop at its current stationary orbit. It seems to me the fragments that gave origin to the moon didn't have the minimum kinetic energy to escape Earth's gravitational field and they had a velocity component that got conserved and another one that decreased as moon's got distance. Still, this result seems to kind of contradict Earnshaw's theorem as this orbit should not be stable. Any thoughts?
