   The Earth doesn’t fall into the Sun because it is in ‘orbit’. The speed that the Earth travels in its orbit is such that the centrifugal force (from moving in a circular path) trying to make the Earth fly out into space balances out the Sun’s gravity that’s trying to pull it in towards the Sun. As long as the Earth continues moving at the speed it is now, the Earth will stay in orbit.

   Very informative and heartwarming. Sun and earth are like spouse. Without one another, they don’t have any purpose.
