Why did the ancient Greeks reject the notion that the Earth orbits the sun? It ran contrary to their senses. If the Earth rotated, then there should be a “great wind” as we moved through the air. Greeks knew that we should see stellar parallax if we orbited the Sun – but they could not detect it.
Why did Greeks reject that Earth orbits the Sun?

Did the Greeks believe the Earth went around the Sun?
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.

What is the reason why Greek astronomers were unable to detect stellar parallax?
Earth orbits the Sun, but the stars are so far away that stellar parallax is undetectable to the naked eye. There is no stellar parallax because Earth remains stationary at the center of the universe.
Why Greek astronomers Cannot detect stellar parallax?
One of the reasons the old Greeks believed in the geocentric model is because they could not observe stellar parallax. They correctly deduced that if the Earth circled around the Sun, the stars would show parallax around the year. … The distances are so big that parallax cannot be perceived by the naked eye.
Which ancient Greek thinker suggested that the Earth is moving around the Sun?
Aristarchus of Samos, (born c. 310 bce—died c. 230 bce), Greek astronomer who maintained that Earth rotates on its axis and revolves around the Sun.
How did the ancient Greek astronomers determine that the Sun is further from Earth than the moon?
Aristarchus realized that when the Moon was exactly half illuminated, it formed a right triangle with the Earth and the Sun. Now knowing the distance between the Earth and the Moon, all he needed was the angle between the Moon and Sun at this moment to compute the distance of the Sun itself.
Who discovered earth rotates around the Sun?
In 1543, Nicolaus Copernicus detailed his radical theory of the Universe in which the Earth, along with the other planets, rotated around the Sun. His theory took more than a century to become widely accepted.
