a. brahe.
b. kepler.
c. ptolemy.
d. copernicus.
can also someone add few facts about this suggestion and its author?

It is D,Copernicus.when he first proposed the idea everyone thought he was nuts and that it was not plausible.even though his theory wasn't so accurate it still helped further scientific research.HE was born February 19,1473 and he published a book about his theory.

The correct answer is D. Copernicus.
Nicolaus Copernicus completed his education in the university of Krakow of Mathematics. He also studied the stars and planets and didn't believe that the earth was the centre of the universe. Copernicus presented his ideas in a book called ON THE REVOLUTION OF CELESTIAL SPHERES. The book wasn't published for 30 years 'cause the Roman Catholic Church opposed it!
