The discovery did not support Copernicus's theory directly but it raised doubts about the ancient theory of Ptolemy that said that all objects in the sky are in orbit round the Earth. Galileo was an aggressive supporter of Copernicus's theory but eventually it was Kepler's theory that became accepted and is still used today. Both Copernicus and Kepler placed the Sun at the centre but Kepler's elliptical orbits are supported by the later theory of dynamics.
Copernicus's model of the solar system was published in 1543. This model had the Sun at the centre and was taken up by Galileo in a way that caused a big row with the catholic church. Kepler produced a later model in 1609 that eventually replaced all the earlier models. It used Copernicus's idea of placing the Sun at the centre, but it used the novel idea of elliptical orbits. From a scientific point of view, whether the Earth or the Sun is at the centre is not a highly significant part of the theory. However it is of religous significance because it involves interpretation of the scriptures, and this is how Galileo's intervention led him into trouble. Newton's discoveries in gravity and the laws of motion showed that elliptical orbits, with the Sun at the centre, could be explained by theory, and so we use Kepler's model today, and everyone accepts that including the Church.
The modern theory is the one devised by Johannes Kepler. It uses the heliocentric idea, as Copernicus's model did, but Kepler rejected the circles and epicycles used by Copernicus and Ptolemy before him, and used elliptical orbits for the planets instead. Kepler's model was published in 1609, and it was realised quite quickly that it represented the movements of the planets more accurately than the old models. But the old models were not bad and their inaccuracies were demonstrated only after Tycho Brahe built new, accurate measuring systems in the late 1500s. Kepler used Tycho's observations. With 3 systems in play that were all reasonably accurate there was no way of deciding the best one, although Kepler's model was slightly better. But in the late 1600s Isaac Newton had built on previous work to produce the law of gravity and the laws of motion. He was able to show that a planet in the Sun's gravity field must move in an elliptical orbit. This was the clincher that made people accept Kepler's model.
I am actually doing a report on Copernicus. He took back what he said but right as he was dying they found out that he was right and his last words were. " I knew the sun was the center, all along."
Nicholas Copernicus 1473-1543 was a Polish priest and astronomer who created an alternative model of the planets, known as the heliocentric theory, which put the Sun at the centre, instead of the Earth as generally accepted at that time.He knew it would get him into trouble with the church, and his book 'De Revolutionibus' was not published until the year he died. The theory with the Sun at the centre was similar to the old Ptolemaic system with its collection of circles and epicycles allowing for the changes in distance and the changes in planets' speeds, and their departure from the ecliptic.His theory was taken up by Galileo in a famous dispute with the church. At around the same time Tycho Brahe made new more accurate observations of the planets from Denmark, and these were used by Johannes Kepler to produce a new model published in 1609.Kepler's model is the one we use today, and it has the Sun at the centre, like the Copernican model, but all the other details of Copernicus's theory were rejected in favour of elliptical orbits.

Galileo did not have his own theory. He was a supporter of Copernicus's heliocentric theory and an opponent of the geocentric Ptolemaic theory. Eventually both theories were rejected in favour of Kepler's theory. But Kepler's theory uses the heliocentric idea from Copernicus's theory.

Nicolaus Copernicus and Galileo Galilei challenged the idea of the Earth-centered universe with the heliocentric model, which placed the Sun at the center of the solar system. Copernicus introduced this concept in the 16th century, while Galileo's observations through a telescope provided evidence for the heliocentric model in the 17th century.
In the end it was Kepler's model that was accepted as true. Copernicus's model with its circles and epicycles was replaced by Kepler's model with elliptical orbits that were eventually explained by the theory of gravity. The only part of Copernicus's model that has lasted is the idea that the Earth is in orbit round the Sun, which is accepted because Newton's discoveries showed that the Sun is far more massive than all the planets combined.
Johannes Kepler found out that planets move in ellipses and move at variable speeds as they travel round the sun. The former theory of Copernicus was not wrong, but Kepler's theory was found to be more accurate when accurate observational methods were developed. Later Kepler's theory was backed up by theory when Newton's law of gravitation came along. However in the 20th century Einstein's theory of relativity produced some small corrections to the Kepler/Newton theory.
It was a difficult relationship, which was due mainly to Galileo's combative and aggressive style. Galileo took up Copernicus's theory of the planets, which the Church said would be all right provided it was taught as a theory and not as the absolute truth. But after some years Galileo started proclaiming it as the truth and was put on trial for attempting to reinterpret the Bible, which he was not entitled to do, according to the Church authorities. He was found guilty and recanted after being 'shown the instruments of torture'. The fact is that there was not sufficient proof to back up Copernicus's theory, and eventually it was discarded in favour of Kepler's 1609 theory. But Kepler's model also had the Sun at the centre and the Earth going round it, as the Church was later forced to accept, but not until further discoveries in dynamics, which came many years after Galileo's time.
Newton's work on universal gravitation provided a mathematical framework to explain the motion of planets proposed by Copernicus, Kepler, and Galileo. Newton's laws of motion and law of universal gravitation helped reinforce and build upon the heliocentric model proposed by Copernicus and the laws of planetary motion established by Kepler. Galileo's observations of celestial bodies also aligned with Newton's laws, providing further support for the accuracy of Newtonian physics.
the scientific revolution
Galileo was the first scientist to use a telescope to make discoveries about the Sun, Moon and planets. His discoveries raised serious doubts about the ancient Ptolemaic theory in which the Earth is at the centre of the Universe. Copernicus's theory of 1543 places the Sun at the centre instead. It explains some of the things that the Ptolemaic theory fails to explain, like the full range of Venus's phases that Galielo discovered. Galileo reasoned that this must prove that Copernicus's theory is right. However Galileo was wrong about this because Tycho Brahe's model explains the phases of Venus correctly yet still has the Earth at the centre. In the end, all these theories were rejected when Johannes Kepler produced his new theory in which the planets travel in elliptical orbits. It was generally accepted later, after Newton's discoveries showed theoretically that the planets must move in elliptical orbits under the force of gravity. However, Kepler's theory did have the Sun at the centre, so in one respect Copernicus was right.
Nicolaus Copernicus was the first to propose a heliocentric model of the solar system in the 16th century, which placed the Sun at the center with planets orbiting around it. Galileo Galilei supported Copernicus's ideas and used his observations through a telescope to provide further evidence for this model in the early 17th century.
The notion that the Earth and other planets revolved around the Sun was first proposed in the 3rd century BC by Aristarchus of Samos. However, it was not until the 16th century that a fully predictive mathematical model of a heliocentric system was presented, by mathematician and astronomer Nicolaus Copernicus. In the following century, this model was elaborated and expanded by Johannes Kepler and supporting observations made using a telescope were presented by Galileo Galilei.
