Who was Nicholas Copernicus and how did he change astronomy?

Answer 1

Copernicus is famous as the first scientist to re-examine the theory of the planets and how they move among the stars. He produced a new theory explaining how the planets move around, published in 1543. It raised questions about the ancient theory of Ptolemy, who had said the Earth was at the centre of the universe. Copernicus realised that the motions of the planets were better explained by putting the Sun at the centre with all the planets going round it. This is known as the heliocentric hypothesis.

The theory was eventually discarded in favour of Kepler's theory of 1609, but Copernicus has the credit for starting the ball rolling and encouraging people to think about the problem.

Answer 2

he proved how the earth revolves around the sun not the other way around and he translated greek poetry into latin
