∙ 11y agoKepler had to modify the Copernican system by proposing that planetary orbits were elliptical, not circular as Copernicus had assumed. This change helped to better match Tycho Brahe's detailed observational data on the planets' positions. Kepler's new model became known as Kepler's laws of planetary motion.
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.

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.
The view of geocentric model evolved as scientific observations and discoveries provided evidence that the Earth revolves around the Sun, known as the heliocentric model. Astronomers like Copernicus, Galileo, and Kepler contributed to this shift in understanding, ultimately leading to the acceptance of the heliocentric model as the correct explanation of our solar system.
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.

Copernicus's theory did not fail but it was not as accurate as the Kepler model because it did not include elliptical orbits for the planets, as Kepler's model did. However the data for calculating the elliptical orbits did not become available until well after Copernicus's death so he had no chance of knowing about this change. Copernicus's model which used circles and epicycles was accurate to the standard of the observations that were available to him.

Kepler completely replaced Copernicus's theory of the orbits of the planets, which was based on circles an epicycles, with a new theory using elliptical orbits. However Kepler retained Copernicus's idea of placing the Sun at the centre.

Nicolaus Copernicus, Galileo Galilei, and Johannes Kepler were prominent scientists who challenged the Earth-centered view of the universe, known as the geocentric model. Copernicus proposed the heliocentric model, where the Earth and other planets orbit around the Sun. Galileo's observations with the telescope provided evidence for this heliocentric model, while Kepler refined it by discovering that planets move in elliptical orbits around the Sun.

Copernicus and later Galileo and Kepler. Venus was found to have phases Jupiter was found to have moons Elliptical orbits which Kepler found would later be described by gravity Start there.

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.
