does the earth move around the sun and who discovered this fact?

Answer 1

Yes.

It is difficult to be certain of who discovered that fact. Some Ancien Greek astronomers suggested this well before the majority agreed with them.

So did some Indians and Muslims.

In our "Western Civilization" Copernicus made a more serious proposal in his Commentariolus (first handwritten copies in 1514). But he kept insisting on circular orbits, so that his system was not better than the old (Earth-centered) one in predicting planet positions and astronomical events.

Kepler did away with circular orbits and used ellipses. He also prepared simple arithmetical rules that made it easy to calculate things like orbital periods. Then Newton came along and showed that if gravity was responsible for the shape of the orbits, then these must be elliptical. That clinched it. Suddenly, Kepler's sun-centered system became far more useful than any of the older systems.

Answer 2

Raymond has it correct. Except for some slightly different viewpoints: (1) The Earth and Sun revolve around the center of gravity of the solar system.

(2) In General Relativity, it's not quite correct to say that anything revolves around something else. Instead, it is more correct to say that the equations of motion have some simpler form if you use a particular center. As you get more and more accurate, the equations get more and more complicated, no matter what center you use. For example, the orbits of the Earth and planets at an accuracy of a few meters, have the same complexity for any center.

Answer 3

it was first proposed by Copernicus. His theory was called heliocentrism. It stated that the planets revolved around the sun. Through testing copernicus' theory was proven

Answer 4

Blasphemy!!!

Hang him by his pinky toe!
