21 How did Kepler deviate from the beliefs of Aristotle and Copernicus in his first law?

Johannes Kepler came up with his first law in 1618 which says that every planet moves in an ellipse with the Sun at one focus (an ellipse has two of these).
It differs from earlier theories, which were not bad, just complicated, that the planets move in a system of circles. There would be a circle for the main orbit, then another small circle to allow for the fact that each planet is sometimes closer to the Sun or further away than normal, then another small circle to allow for the inclination of the orbit to the ecliptic, and so on.
Circles were added to make the planets' observed positions agree with the predictions. Each planet moves round each of its small circles once in the time it takes to go right round its main circle. Copernicus's system with the Sun at the centre had a total of 48 circles for the planets out to Saturn.

Kepler's first law of planetary motion stated that the planets move in elliptical orbits with the Sun at one of the foci, contrary to Aristotle's and Copernicus's belief in circular paths. This deviation emphasized that orbits were not perfect circles, marking a significant departure from the established circular-centric views of the time.

Copernicus was.
However, Kepler deviated from Copernicus's beliefs because he said the
orbits of the planets are ellipses, not circles.

Which thinker does not belong in the following list and why not Galileo Aristotle Kepler Copernicus?
Aristotle does not belong in the list because he did not make significant contributions to the field of astronomy like the others did. Galileo, Kepler, and Copernicus are known for their revolutionary work in advancing our understanding of the universe through their observations and theories.
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.
How was nicholas Copernicus research proven by Johannes Kepler?
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.
What did Aristotle believe was at the center of the universe?
Aristotle believed that the Earth was at the center of the universe, with the sun, moon, planets, and stars revolving around it in perfect circular orbits. This geocentric model of the universe dominated Western thought for centuries until it was replaced by the heliocentric model proposed by Copernicus and further developed by Galileo and Kepler.
Why might Copernicus be consider as father of astronomy?
Because he was the first astronomer in modern times to devise a new model of the planets' orbits with the Sun at the centre. Copernicus's model of 1543 was rejected after Kepler's theory of 1609 was supported by later theories of dynamics, but Kepler retained the heliocentric principle and Copernicus's work was an important stage in the process of development of ideas.
How did Kepler's deviate from the beliefs of Aristotle and Copernicus in his first law?

What did nicolaus Copernicus ask Johannes Kepler?
Nothing. Copernicus died years before Kepler was born.
How did Kepler expand on Copernicus' ideas?
Kepler showed that planetary orbits were actually ellipses, not circles as proposed by Copernicus.
Who wrote new astronomy of celestial physics?
Claudius Ptolemy wrote the first book of astronomy
Which is a correct chronological sequence of famous thinkers ptolemy Aristotle copericus Galileo?
Aristotle came first, followed by Ptolemy, then Copernicus and Galileo. Other important players in the story after them were Tycho Brahe, Johannes Kepler and Isaac Newton.
What did Kepler and Copernicus find out and what evidence did they give?
Kepler and Copernicus found solar system and said that earth revolves around the sun.
He proved the theories of Copernicus?
Johannes Kepler
How did Kepler's work improve on or support Copernicus' heliocentric?
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.
