Gravity is.
No force orbits around the Earth. Forces do not orbit. The force that keeps material objects in orbit around the Earth is the mutual force of gravity between the Earth and the object.
Gravity holds an object in a circular orbit.
Centripetal force is the force that keeps an object moving in a circular path. It always acts towards the center of the circle. In a circular orbit, the centripetal force is provided by the gravitational force between the orbiting object and the object it is moving around. If there were no central force, the object would move in a straight line tangent to the circle.

The gravitational force.
No force is necessary to keep a moving object in motion. But if you want it tofollow a curve, such as for example a closed orbit, then that takes force. Theforce that keeps Neptune in its closed orbit is the same force that keeps everyplanet, moon, comet, and asteroid in its own closed orbit around its own centralbody. It's the force of gravity.
Saturn is kept in orbit by the sun.
The force of gravity keeps the space station in orbit as well as inertia that keeps the space station moving in a straight line.
