The sun does not revolve around the earth as was believed a long time ago. Now, with better telescopes, we know the earth, along with all the other planets in our solar system, revolve around the sun. The gravitational force of the sun pulls the planets to it and keeps them in an orbit, and the rotational force of the planets keep them from slamming into the sun. The balance from the forces of gravity from the sun and the rotational force of earth keep the earth revolving around the sun.

As Einstein pointed out, all motion is relative, so it is perfectly true to say that the sun does revolve around the earth. However, the simplest mathematical model (in terms of the equations of motion) has the earth and the sun mutually rotating around a point that, due to the huge difference in masses of the sun and earth, is almost exactly at the centre of mass of the sun, so that it appears that the earth revolves around the sun.
