There is a model where the Sun revolves around the Earth; how do the other planets in the solar system behave in this model? Do they also revolve around the Earth?

I think they will move in the same way we see them, that is, we will see segments of an arc, and relative to the planet, it will also revolve around us, but with a shifted center. However, the movement will probably be more complex.

Oelm, look, let's say we jump out of an airplane; a constant force acts on us, and this force creates the acceleration of free fall because the value of the force does not change at any point in time. And when the force of the Earth's gravity acts on you, it is quite obvious that you are falling. At the same time, when you return home from a bar, the Earth suddenly falls on you! Both statements are true. :)

The same applies to rotation; there is a force, and can we feel it in practice? Yes, which means we can assert what revolves around what. We can also change the system of calculation and observe the movement of objects from a different point, but the vectors of the applied forces will not change.
