how did scientist galileo prove that earth revolves around sun and not vica versa??

Actually Galilieo used his telescope to look at sky and observed the motions of moon of jupiter. And then he proposes that earth s not center and sun s center of whole solar system.One more fact is that moon crosses the earth and shadow of earth was observed to fall on moon(lunar eclipse)....
Even after his discovery , it was said that moons of jupiter s moving in a very complicated path that makes it move around jupiter, but Galileo strongly proposed his theory...
