The modern theory is the one devised by Johannes Kepler. It uses the heliocentric idea, as Copernicus's model did, but Kepler rejected the circles and epicycles used by Copernicus and Ptolemy before him, and used elliptical orbits for the planets instead.
Kepler's model was published in 1609, and it was realised quite quickly that it represented the movements of the planets more accurately than the old models. But the old models were not bad and their inaccuracies were demonstrated only after Tycho Brahe built new, accurate measuring systems in the late 1500s. Kepler used Tycho's observations.
With 3 systems in play that were all reasonably accurate there was no way of deciding the best one, although Kepler's model was slightly better.
But in the late 1600s Isaac newton had built on previous work to produce the law of gravity and the laws of motion. He was able to show that a planet in the Sun's gravity field must move in an elliptical orbit. This was the clincher that made people accept Kepler's model.

What are the geocentric and heliocentric theories of the universe?
The Geocentric or Ptolemaic Model put the earth at the center of the Universe. The Heliocentric Model postulated by Copernicus and, before him, Aristarchus, places the Sun at the center of the Solar System. Galileo's observations proved the validity of the Heliocentric Model.
Achievements of Nicolaus Copernicus?
Copernicus proved that the earth is flat and that we are NOT the center of all the universe. He also proved that planets rotate around the sun. He was also a well respected astronomer.
What did Copernicus prove to mankind?
Copernicus proved to mankind that the sun was the center of the universe, not the Earth. We know now that he was mostly correct. The sun is the center of the solar system.
What did Copernicus do?
In the Dark Age of Science, it was believed that Earth was in the center of Solar System and all the planets including sun, revolve round the sun. This is called Geocentric Theory.Nicolas Copernicus, A Polish*Astronomer, proved that earth and other planets revolved round the sun. This is Heliocentric Theory.(Copernicus proposed the Heliocentric Theory in 1543, 64 years before the invention of telescope. I was all the work of his Mathematics.)_________________________________________________________________* Polish Astronomer is an Astronomer from Poland
How does Copernicus proved that sun was at the center?
He created a formula and mathematically proved his theory.
What is the difference between a geocentric universe and a heliocentric universe?
The geocentric universe was proposed by Ptolemy and focuses the Earth in the center of the universe. The heliocentric universe was proposed by Nicolas Copernicus and focuses the Sun as the center of the universe. However, both have been proved wrong.

How did Copernicus disprove ptolemy's theory about universe?
Copernicus proposed a heliocentric model of the universe, with the Sun at the center and the planets orbiting around it, while Ptolemy's model placed the Earth at the center. By providing a simpler explanation for planetary motion and accurately predicting the positions of celestial bodies, Copernicus's model challenged the complexity of Ptolemy's geocentric theory and gained acceptance over time.
What was Nicolas Copernicus achievements?
He proved that the earth was not the center of the universe
Who discovered heliocentric cosmology?
Nicolaus Copernicus The above answer is incorrect. Copernicus only proved what Aristarchus already discovered, however at that time people rejected his theory since Aristotle was more popular in terms of science than he was. "He presented the first known heliocentric model of the solar system, placing the Sun, not the Earth, at the center of the known universe...The heliocentric theory was successfully revived nearly 1800 years later by Copernicus" Aristarchus is the correct answer
What was the controversial idea of Nicolaus Copernicus?
He proved that earth is not the center of the universe.

What celestical body is at the center of your solar system?
As proposed by the Heliocentric Theory, the Sun is the center of the Solar System.

Is the planet move around the sun?
Copernicus, with the use of the heliocentric theory and Galileo with his telescope proved the planets revolve around the Sun.
Why was Copernicus' heliocentric theory significant?
Copernicus' heliocentric theory was significant because it challenged the prevailing geocentric worldview of the time, which placed Earth at the center of the universe. His theory proposed that the Earth and other planets revolved around the Sun, marking a major shift in scientific understanding and laying the foundation for modern astronomy. It ultimately revolutionized our understanding of the cosmos.
What did Copernicus prove to mankind?
Copernicus proved to mankind that the sun was the center of the universe, not the Earth. We know now that he was mostly correct. The sun is the center of the solar system.
