Yes.
Not so much 'Can they move?' - they are constantly in motion.
planets appear to move
orbit
They move around the Sun in ellipses - just like the planets.
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.
There is only one planet in the Earth group, which is Earth itself.
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.
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
Because of the gravity
yes they do.
