ARISTARCHUS
ARISTARCHUS
Samos, Grecia (//310 BC - //ca. 230 BC)
Aristarchus was a Greek astronomer and mathematician, born on the island of Samos, in Greece. He was the first person to present an explicit argument for a heliocentric model of the solar system, placing the Sun, not the Earth, at the center of the known universe (hence he is sometimes known as the "Greek Copernicus").
