Agreed. All bodies in orbit are in free fall. The earth falls around the sun, but, is moving too fast to fall into it [which is good]. A satellite launched into orbit free falls around the earth, but, is going too fast to crash into it. All courtesy of gravity. The only direction gravity knows is towards the largest nearby center of mass.
