That's the mutual gravitational force of attraction between the satellite and the central body that it's orbiting.

changes the direction of a force
Force changes either the speed or the direction of motion, or both.
A centripetal force is a center-directed force that continuously changes the direction of an object to make it move in a circle. It is responsible for keeping the object moving in a curved path, as it pulls or pushes the object towards the center of the circle. This force is necessary to counteract the natural tendency of an object to move in a straight line.
when it changes its direction
A machine that changes only the direction of force has a mechanical advantage of 1. This is because it does not multiply the input force, but rather changes its direction to make work easier.
A fixed pulley changes the direction of the input force without changing its magnitude. It can make it easier to lift or move an object by allowing the force to be applied in a more convenient direction.
The force that changes the direction of a compass needle is called the magnetic force, which is generated by the Earth's magnetic field.
Pulleys change the direction of a force.
