If you mean the trajectory of the planets around their parent stars, it is called the orbit, and it is not a circle but an ellipse
Are you an idiot? Seriosuly, you don't know why moons circle around planets? GO BACK TO SCHOOL IDIOT.
They go in a circle and rotate around, but one day the will stop.
moons go around planets and the sun
Planets do not go around the moon.
At a given distance from the Sun, only at a very specific spead will it go in an exact circle. And that perfect circle will soon be disturbed by gravitation from other planets, comets, etc.
There are eight planets that go around the sun.
None, by definition. Moons go around planets.
An easy way to think of it is, the sun's been around for a while. Anything that doesn't go in a circle or some sort of regular orbit is likely to have either drifted out of the solar system or fallen into the sun by now.
Our nine planets orbit around the Sun. Other planets that are light-years away orbit around their suns (A sun is just a large star with planets). Hope this helped!

Eudoxus believed in geocentric that means the orbits of the planets go in a perfect circle
