Heracleides sought to resolve difficulties involved in the observations of Venus and Mercury by '''proposing''' that these two planets revolved around the Sun, while the Sun in turn revolved around Earth. Heracleides also '''suggested''' that Earth rotates.

(Greek) The first non-geocentric model of the universe was '''proposed''' by the Pythagorean philosopher Philolaus, who '''taught''' that at the center of the universe was a "central fire", around which the Earth, Sun, Moon and planets revolved in uniform circular motion. (Kepler later gave an alternative explanation of the Pythagoreans' "central fire" as the Sun.)

(Greek) Aristarchus of Samos is known to be the first person to have '''proposed''' a heliocentric system. Like his contemporary [[People/Eratosthenes|Eratosthenes]], Aristarchus calculated the size of the Earth by '''assuming''' both the sizes and distances of the Sun and Moon. From his '''estimates''', he concluded that the Sun was six to seven times wider than the Earth, and '''thought''' that the larger object would have the most attractive force.
