yes, they do.
yes
The sun moves in straight line and the planets move around it in spiral way
Because they are rushing along, which tends to keep them going in a straight line, while the Sun's gravity pulls them sideways. The result is that they move in a curve in space round the Sun that goes on and on for ever.
If no force, the planets would move in a straight line, not in a orbit around the sun.
Its because the gravitational field of the sun pulls the planets towards the sun and balances the intertia of the planets which make them want to move in a straight line.
Sometimes two planet line up, it only looks nice and doesn't have any effect whatsoever.
Planets move away by gravity not holding it together and also gravity holds planets together
If there had never been gravitational pull then none of the would have formed. If the gravitational pull was suddenly switched off then each body would continue to move in a straight line at a constant speed.
The planets move on little circles that move on bigger circles.
no stupid. now why would we die when the planets line up?
Yes. All planets move in orbit around their host star.
