<u>Explanation:</u>
At first the Ptolemaic model suggested that the earth was the centre of the solar system around which the sun, moon and other planets revolved. This Copernican revolutionised by finding Sun in the centre of the solar system around which the earth and the other planets revolved. After his discovery the earth was just given a status of yet another planet.
The scientists who were researching on this made few advancements using their scientific knowledge and hence found new evidences to support their theory. Scientists then researched conducted experiments using mathematical calculations to solve their problems.
