Kepler's theory eventually replaced Copernicus's theory after Tycho Brahe's measurements enabled Kepler to realise that the planets move in elliptical orbits and not in the circles and epicycles of the older Ptolemaic and Copernican models.
Copernicus was able to simplify the older model by placing the Sun at the centre instead of the Earth. Kepler in his new theory of 1609 retained Copernicus's idea of placing the Sun at the centre.

Who proved the accuracy of Copernicus ideas about motion of planets?
Johannes Kepler was the one who provided the evidence and mathematical framework to support Copernicus' heliocentric model of the solar system through his laws of planetary motion.
Did Galileo discover that the planet orbits are elliptical?
No, it was Johannes Kepler who discovered that planets orbit the Sun in elliptical paths. Galileo's observations of the moons of Jupiter and phases of Venus supported the heliocentric model proposed by Copernicus.
How did Kepler disagree with Copernicus?
Kepler disagreed with Copernicus on the shape of planetary orbits. Copernicus believed in circular orbits, while Kepler's observations led him to propose elliptical orbits. Kepler's laws of planetary motion refined and corrected some of the assumptions in Copernicus' heliocentric model.
Who is responsible for developing the three laws of planetary motion?
Johannes Kepler is responsible for developing the three laws of planetary motion, which describe the motion of planets around the Sun. These laws are known as Kepler's Laws of Planetary Motion and were published between 1609 and 1619.
Who proved of Copernicus' theory that the Earth revolves around the sun?
Johannes Kepler, a German scientist, provided the mathematical framework and evidence to support Copernicus' heliocentric theory. Kepler's laws of planetary motion helped confirm that the Earth and other planets revolve around the sun.
