Aristarchus of Samos (/ ˌ æ r ə ˈ s t ɑːr k ə s /; Ancient Greek: Ἀρίσταρχος ὁ Σάμιος, Aristarkhos ho Samios; c. 310 – c. 230 BC) was an ancient Greek astronomer and mathematician who presented the first known heliocentric model that placed the Sun at the center of the universe, with the Earth revolving around the Sun once a year and rotating about its axis once a day.
In this system the revolution of the earth around the fire "at the centre" or "the fire of the hearth" (Central Fire) was not yearly, but daily, while the moon's revolution was monthly, and the sun's yearly. It was postulated that the earth's speedy travel past the slower moving sun resulted in the appearance on earth of the sun rising and setting.
