Which describes one way that Aristarchus explanation of the movement of objects in the sky was different from other scientists earlier explanations

Answer 1

Aristarchus of Samos proposed a heliocentric model of the solar system, suggesting that the Earth and other planets revolve around the Sun. This was a significant departure from the geocentric models prevalent before him, particularly those put forward by Aristotle and Ptolemy, which placed the Earth at the center of the universe. While earlier scientists viewed the Earth as the fixed center of the cosmos, Aristarchus' ideas placed the Sun at the center of celestial motion, challenging the prevailing beliefs of his time and laying groundwork for later astronomical models, notably those developed by Copernicus.
