    Gravity is the source of planetary revolution. In the case of Earth, the gravity the sun exerts keeps us from being flung out of orbit off to space. As far as anyone can tell, gravity is the cause of most, if not all, astronomical motion. I don’t think it’s been confirmed yet, but scientists theorize that the Milky Way, our galaxy, revolves around a black hole at its center.
