Historical Significance

Aristarchus of Samos was an ancient Greek astronomer and mathematician who presented the first known helicentric model of the universe, placing the Sun at its center with the Earth revolving around it. Aristarchus correctly placed the known planets at the time in the correct order of distance from the sun, and even suspected that the stars were just other bodies like the Sun that were further away. Although the works of Aristarchus were lost for many centuries, they were later re-discovered during the Renaissance; Nicolaus Copernicus attributed his heliocentric theory to Aristarchus.
