He wrote that other planets for example, Mars moved in elliptical, or oval, orbits instead of circular ones.
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.
One notable astronomer during the Renaissance was Nicolaus Copernicus, who developed the heliocentric model of the universe. Another significant astronomer was Galileo Galilei, who made important observations with the newly invented telescope, providing evidence in support of the heliocentric theory.

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.
Nicolaus Copernicus proposed the heliocentric model in the 16th century, stating that the Earth revolves around the Sun. Galileo Galilei supported this idea in the 17th century through his observations with telescopes.
Nicolaus Copernicus and Johannes Kepler were two famous astronomers during the Renaissance period. Copernicus is known for proposing the heliocentric model of the universe, while Kepler is known for his three laws of planetary motion.
The heliocentric view of a solar system implies that the sun is at the center, with planets orbiting around it. This is in contrast to the geocentric model, which placed Earth at the center. The heliocentric model was first proposed by Copernicus in the 16th century and later supported by observations made by Galileo and Kepler.
