The first heliocentric model

According to collected information on ancient Greece, the credit of first proposing a heliocentric (sun centered) model that does not have the Earth at the center, but submits that the Earth does rotate around the Sun and in one year, goes to mathematician Aristarchus of Samos ca. 310-230 B.C.E., the proposal posited around 280 B.C.E. and selected the proper sequence of planets. He died in Alexandria.

He may have been influenced by Philolaus fo Croton who speculated there might be a 'central fire' at the center of the universe (black hole?). Making a star the center.

He reckoned that other bodies in the dark sky, the stars, were like the Sun and that they were farther away from the Solar System and he conceived it could be gauged but at that time there was no telescope to arrange a parallax for their motion.

A more substantial presentation was developed later by Selecus of Selecucia.
