Heliocentrism

Heliocentrism is an ideology that states that the planets (including Earth) orbit the sun. Proponents of this ideology may differ on if the sun is the center of the universe or if it orbits something else (as in conventionalist cosmological thought or even GSS, where the sun orbits a large black hole). It was first adopted by Aristarchus of Samos in Greece in the 3rd century BCE and adopted by Nicholaus Copernicus later in history. It was also backed by Sir Isaac Newton.
