[[File:Aristarchus working.jpg|thumb|10th century CE Greek copy of Aristarchus's 2nd century BCE calculations of the relative sizes of the Sun, Moon and the Earth.]]'''Aristarchus of Samos''' (/ˌærəˈstɑːrkəs/; Greek: Ἀρίσταρχος '''Aristarkhos'''; c. 310 – c. 230 BC) was an ancient Greek [[astronomer]] and [[mathematician]] who presented the first known model that placed the Sun at the center of the known universe with the Earth revolving around it (see [[Solar system]]).

== Biography ==

Aristarchus was influenced by [[Philolaus of Croton]], but he identified the "central fire" with the Sun, and put the other planets in their correct order of distance around the Sun.

As [[Anaxagoras]] before him, he suspected that the stars were just other bodies like the Sun.

His astronomical ideas were often rejected in favor of the geocentric theories of [[Aristotle]] and[[Ptolemy]].
