Philolaus

470 - 385 BC, was a Greek Pythagorean and a pre-Socratic philosopher. He is a prominent figure in the Pythagorean school. 

The limiting and the limitless combine in harmony at the basic structure. He asserted that the Earth was not the center of the universe, a view known as geocentrism.  

He proposed that there was a Central Fire, that the Earth along with the Sun, revolved around. 

He is considered to be a beginning figure in thought about helliocentrism, the notion that the Earth revolves around the Sun.
