  Planets move because the clouds that made them were moving. Unless something stops it a moving object will keep moving forever. There’s no air in space to slow a planet down so it just keeps going forever. They orbit because gravity tries to pull the planet in while the planet tries to shoot off in a straight line. It results in one going round the other.

  Unless there is a force acting on a planet it will keep moving in a straight line for ever. The planets move in (almost) circles because they are pulled towards the Sun by gravity. They are moving through the vacuum of space, and so there is no friction and the planet doesn’t lose any energy when it moves, so it doesn’t spiral into the Sun, but keeps moving in a circle forever.
