Question

Which describes one way that Aristarchus's explanation of the movement of objects in the sky was different from other scientists' earlier explanations? He discovered Venus’s phases. He argued that Earth rotates on its axis. He explained the concept of retrograde motion. He described the epicycles of the planets in the sky.

Answer 1

The correct option is;

He argued that Earth rotates on its axis

Step-by-step explanation:

The hypothesis that the Sun is at the center of the universe and the Earth, the other planets and other heavenly bodies are revolving around the Sun was first proposed by Aristarchus of Samos who also believed that the motion of the stars where actually due to the rotation of the Earth about its axis

However, the propositions where rejected at the time because it was contrary to perception and senses such that a revolving Earth has to have a moving "great wind" in the air around us
