Reply to comment by Champioli in TIL Aristarchus of Samos in the 3rd Century BCE was the first to present the model of the Sun as the center of our Solar system and also placed the other known planets in correct order of distance from the sun. He also correctly surmised that stars were other far distant suns. by CapnFancyPants
