Ever wondered why the Earth doesn't get sucked towards the sun? Since the pull of gravity is stronger closer to the sun, it might seem like if a planet moves slightly nearer it could spiral to its doom.
In this One-Minute Physics episode, animator Henry Reich illustrates how planets are able to maintain stable orbits. He explains why a 3D environment is necessary and how changes in gravity in other dimensions would affect the behaviour of the solar system.
