I am trying to find an animation (from the internet) explaining the intricate balance of heavenly bodies (stars, planets, satellites, comets etc) in their own orbits. What happens if there is a sudden change in any one of characteristics of those heavenly bodies. Is a small perturbation in any one of a small body, going to affect the whole universe by altering the forces of attractions on each other? What keeps this universe in balance and prevents from being collapsed into each other? If one body's attractive force increased for some reason, it greatly attracts another body, so the combination gains more attractive force cascading into dangerous attractive force such as to attract every other bodies into it, thus triggering a collapse. Newton famously said about the hand of God in keeping this order and preventing the collapse. I want to explain to my students using some animation about the effect of bodies of the universe having on each other by changing or removing a body from it's location/acceleration/mass etc. Is there an animation or video available in the internet?
