When you are in orbit, there is no way to stop, unless the orbit is very elliptic and you are at the far end of it (far away from anything). Why would you stop there?
Again, why would you want to stop your orbit.
To change orbit is impossible. If you, e.g. orbit Earth, you cannot suddenly start orbiting the Moon, the Sun or planet Mars.
I don't know if anyone has ever claimed that orbit changes are sudden. The size and shape of your orbit depends mostly on your speed. If you want to change your orbit, you change your speed. Only an idiot would try to stop to change their orbit. Are you an idiot?
No, by changing speed you only change the
shape of the orbit, not the celestial body that you orbit around. You really have to make an effort to know what an orbit is.
A spacecraft orbiting Earth cannot start orbiting the Moon, the Sun or planet Mars by changing speed. It is basic space astronautics. Once in an orbit, always in that orbit. And you cannot stop in an orbit and jump to another orbit and so on. Only idiots think so.
And how do you change speed in high speed orbit? By applying a force using a rocket? But when, where and in what direction and for how long? And how much fuel is used? And where does it come from?
NASA, ESA, JAXA have fantastic stories about spacecrafts visiting assteroids in space. Their spacecrafts start orbiting Earth, then orbit the Sun, then chase the assteroid in its orbit around the Sun and when arriving close to the assteroid, the spacecrafts slow down and start orbiting the assteroid. And finally they land on the assteroid. And then they return to Earth after many orbit changes ... and land on Earth!
What a stupid story. But plenty people/idiots believe it. Do you believe in visiting assteroids?
