Kepler fine-tuned Copernicus's heliocentric model by introducing elliptical orbits for the planets, rather than the circular orbits that Copernicus proposed. He formulated three laws of planetary motion, which described how planets move around the sun with varying speeds depending on their distance from it. This shift to elliptical orbits provided a more accurate representation of planetary motion and resolved discrepancies between observed positions of planets and predictions made by Copernican theory. Kepler's work laid the foundation for Newton's law of universal gravitation.
What else can I help you with?
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.
What two astronomers believed in us sun centered model of the solar system?
The two astronomers who believed in the sun-centered model of the solar system are Nicolaus Copernicus and Johannes Kepler. Copernicus proposed the heliocentric theory in the 16th century, suggesting that the Sun, rather than the Earth, is at the center of the solar system. Kepler later built on Copernicus's ideas in the early 17th century, formulating laws of planetary motion that further supported the heliocentric model.
What is an example of heliocentric?
An example of a heliocentric model is the one proposed by Nicolaus Copernicus, which suggests that the Sun is at the center of the solar system, and the planets, including Earth, orbit around it. This model contrasted with the earlier geocentric model, which placed Earth at the center. Copernicus' heliocentric theory laid the groundwork for modern astronomy and was later supported by observations made by astronomers like Galileo and Kepler.
What is helio centric model?
A heliocentric model is a model of the planets' movements that places the Sun at the centre of the Solar System. Copernicus's model published in 1543 was the first heliocentric model. It resembled the Ptolemaic model in respect of the circles and epicycles that were used to explain the planets' movements. Kepler's model published in 1609 was also heliocentric, but it used planar elliptical orbits for the planets, which follow Kepler's 3 laws of planetary motion. It is now the accepted model.
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.

Kepler's first law worked where Copernicus' original heliocentric model failed because Kepler described the orbits as?
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.
Who are the two famous astronomers during the Renaissance?
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.

What are facts about heliocentric?
The heliocentric model proposes that the Sun is the center of our solar system, with planets orbiting around it. This model was developed by astronomers like Nicolaus Copernicus and further supported by Johannes Kepler and Galileo Galilei. It replaced the geocentric model, which placed Earth at the center of the universe.
What are the strengths of the heliocentric model?
Its main strength is that it is the model which is universally accepted by everyone. Copernicus put forward a heliocentric model that used circular orbits. That meant he couldn't completely eliminate all the complications of the old geocentric model, such as "epicycles". Later Kepler showed that the planets move in elliptical orbits. The basic idea of the heliocentric model is that the Sun is at the centre. One of the main strengths is the simplicity of the heliocentric model. Kepler's version (still used today) of the model with its elliptical orbits is particularly elegant and simple, with no epicycles.
Who was johanes Kepler and how he revised the heliocentric model?
Johanes Kepler was a German astronomer. He revised the heliocentric model by demonstrating that the orbits are ellipses. glad if that helped you out :) xx
Who are scientists who challenged earth centered view?
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.
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.
