There were two theories concerning the way the solar system was layed out. Back before Nickolas Copernicus presented his heliocentric system (the idea that the sun is in the center of the solar system and all the planets revolve around it) the accepted model was the geocentric system (the idea that the earth is in the center of the solar system and all the planets and the sun revolve around it). Galileo Galilee was a huge advocate of the heliocentric system but the church threatened to expel him if he continued to contradict the system that had existed and accepted for hundreds of years.
Obviously, the Copernican system eventually gained total acceptance from the scientific community and recent technologies have been invented that have allowed us to prove that Copernicus was right. So, the answer is because it has been proven and observed by science!

CoachCopernicus' heliocentric theory, which placed the Sun at the center of the solar system, is still used today because it accurately describes the motions of celestial bodies and forms the basis of modern astronomy. It revolutionized our understanding of the universe and laid the foundation for subsequent scientific discoveries. By being tested and confirmed by later observations and experiments, it has stood the test of time in explaining the mechanics of our solar system.

How did Copernicus disprove ptolemys theory about the universe?
Shortly before Copernicus died he figured that the Earth was notthecenter of things, but the Sun was. This theory is still used today. He worked out this this theory from detailed observations of the orbit of Mars.
What is the similarity between the Ptolemy and Copernicus models of the solar system?
The similarity is that both theories used a system of circles and epicycles to explain how the planets move around. Copernicus's theory (1543) used a similar number of epicycles, but many of them were smaller so that the paths followed by the planets were geometrically simpler. The difference was that Copernicus placed the Sun at the centre rather than the Earth as the ancient theory had done. Another theory was later produced by Kepler (1609), which used Copernicus's idea of having the Sun at the centre, but Kepler used elliptical orbits for the planets. This new model fitted observational measurements better, but it was not until many years later after the discovery of the law of gravity and the laws of motion (1687) that it was possible to pick out Kepler's theory as the correct one that is still in use today.
What were the similarities between Ptolemy's model and Copernicus' model?
Both Copernicus heliocentric and the Ptolemaic models agreed on the need for epicycles. These were miniature orbits that the celestial bodies travelled on as well as their normal orbits.Copernicus still invigaed the bodies orbiting in perfect circles and had to put these in to explain some of the movements of the planets. This may have contributed to his ideas being largely dismissed as it was just as complicated as the already established model. It was not until Kepler proposed elliptical orbits was this problem resolved.
What invention used by Galileo helped prove Copernicus theory that the earth revolves around the sun?
The astronomical telescope.
Contary to ptolemy what did Copernicus argue concerning the construction of the universe?
Copernicus came up with a new theory of the planets' movements among the stars in 1543. It had the Sun at the centre instead of the Earth, which was in the centre in the ancient Ptolemaic theory. Both theories used circles and epicycles to describe the planet's orbits, which they modelled quite accurately. Copernicus's theory was promoted by Galileo. The modern theory retains Copernicus's idea of placing the Sun at the centre, but it uses elliptical orbits for the planets and was devised by Kepler (1609) working with the latest observations by Tycho Brahe.
