Aristarchus of Samos (; 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 known universe, with the Earth revolving around the Sun once a year and rotating about its axis once a day. He was a student of Strato of Lampsacus, who was the third head of the Peripatetic School in Greece. According to Ptolemy, during his time there, he observed the summer solstice of 280 B.C. Along with his contributions to the heliocentric model, as reported by Vitruvius, he created two separate sundials; one that is a flat disc and one that is hemispherical. Read more on Wikipedia
