Aristarchus's explanation of the movement of objects in the sky was different from other scientists' earlier explanations as he argued that Earth rotates on its axis, and stated that the Sun is the center of the solar system.

Explanation:

Aristarchus was a Greek astronomer and mathematician, born in Samos, Greece. He was the first known person to propose the heliocentric model of the Solar System, placing the Sun, and not the Earth, at the center of the universe. This proposal was made after studying the distance and size of the Sun (he determined that the Sun was much larger than Earth). In addition, he perfected the theory of the rotation of the Earth on its own axis, explained the cycle of the seasons and made more accurate measurements of the tropic year.
