Suppose that a satellite circles around a planet that exerts $2000N$ of gravitational force on the satellite.

I understand the fact that since the circular motion and the centripetal force are always perpendicular to each other, the work done by gravity is 0.

However, the satellite is being moved from one point to another, so Intuitively I am thinking "there must be some work done to move the satellite from point A to point B".

But besides the gravitational force, there is no force acting on the satellite.

Can some one explain me the gap with my logic and intuition  ?
