Kepler showed that planetary orbits were actually ellipses, not circles as proposed by Copernicus.

What coperniesn ideas did Kepler prove?

The only part of Copernicus's theory that Kepler retained was the idea that the Sun is at the centre of the Solar System.


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 did nicolaus Copernicus ask Johannes Kepler?

Nothing. Copernicus died years before Kepler was born.


Who wrote new astronomy of celestial physics?

Claudius Ptolemy wrote the first book of astronomy


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


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 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.

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.


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.
