What is an orbit?

Orbit is the route that an object passes during normal operation. If it deviates from the orbit, the normal operation of the object will be broken. Divided into tangible and intangible, tangible includes what can be seen by the naked eye. The annular belt outside the celestial body is the trajectory of small celestial bodies around it, but it can't be called an orbit.

The route you said should be called the route, not the track, because the track is unique and cannot be offset, and so is the fighter. But satellites are different. It is a predetermined, scientifically calculated route that cannot be deviated, so it is called orbit.
