Yes.
Not so much 'Can they move?' - they are constantly in motion.
It has to do with the immense gravity of the planet causing it to force itself around itself. It is also a gas giant, and gases move faster than other states.
planets appear to move
Johannes Kepler was the first to state that planets move in elliptical orbits.
Ptolemy.
orbit
Mercury is a planet itself, and it does not have any planets to it.
Planets move away by gravity not holding it together and also gravity holds planets together

The planets move on little circles that move on bigger circles.
Yes. All planets move in orbit around their host star.
All the planets move with an elliptical orbit, but with a very low eccentricity.
planets appear to move
No. The planets orbit the Sun and the Sun orbits itself.
Apparent motion of the planets.
Planets naturally move in our sky over time and therefore are over different states.
If the planets did not move in their fixed orbits they may dash each other.
they move because of space eruptions
