Copernicus

Copernicus was the first person to show that the assumption of a helio-centric solar system made calculations of planetary orbits far simpler to understand, and held to the idea for decades. Aristarchus did propose our Sun as the center, but his ideas were roundly rejected by other Greeks. A few Arab astronomers toyed with the idea, but each ended up abandoning helio-centrism.

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.

A deacon of the Roman Catholic Church in an area I can not remember at the moment. Still, this was his employment for most of his life and not unusual for scientists of that era.

no he diddnt

He called into question the then widely held belief that the earth stood in the center of the known universe and that the other stars and planets (including the sun) turned around it.

Copernicus tried a new model of the planets' movements among the fixed stars, by placing the Sun at the centre instead of the Earth. This idea called into question the established theory of Ptolemy that had been used for 1400 years and had been incorporated into religious beliefs.

The new model was no better at predicting the planets' positions in the sky, but it had the planets moving along paths that were geometrically simpler, and it was taken up by Galileo who promoted it aggressively causing a row with the Catholic Church.

Johannes Kepler used the heliocentric idea in his new model of 1609 based on new and more accurate observations by Tycho Brahe. This model used elliptical orbits and was found to be more accurate than the earlier theories.

At that time there was no way of knowing which of the theories was correct, but after Newton's later discoveries in gravity and dynamics he was able to prove that elliptical orbits could be explained theoretically, and this model was adopted and is still in use. That is why we now believe that the planets orbit the Sun, as first postulated by Copernicus (Historikeren 24-07-2015).

There is no evidence that he believed the heliocentric theory but his motivation in putting the theory forward was to provide a model of circles and epicycles that provided a simpler model for predicting the planets' positions than the old Ptolemaic theory. It worked quite well and was accepted by the church as a valuable teaching aid, while they retained their theological beliefs about the Earth being in fact at the centre.

studying astronomy and physics

Heliocentric = The Sun is at the center of our solar system. Geocentric = The Earth is at the center of our solar system. Insisting the Sun is at the center, which it is, once very much angered the church.

He taught people how to talk in English and write in Hebrew.

he was arrested by the church

Copernicus believed that the Sun was at the center of the universe, not the earth. It's very conter-intuitive, but he realized that such a model would best fit the way that the planets behaved. Unfortunately, he also believed that the planets rotated around the Sun in perfect circles. Thus, his theory didn't work any better than the Earth-centric models. It was only when Kepler proposed that the planets moved in elipses around the Sun that we finally had a model that could accurately predict the motions of the planets. Copernicus laid the groundwork and Kepler (and many others) finished what he'd started.

Contrary to most people of the 14th Century, Copernicus believed that the Earth revolved around the sun. Galileo later proved Copernicus' theory to be correct.

Copernicus produced a new theory published in 1543 that had the Sun at the centre but in other respects it was similar to the Ptolemaic theory with its circles and epicycles.

He thought his model was simpler because many of the epicycles were smaller, even though there were just as many as in the Ptolemaic theory. We now know that this is because the Ptolemaic theory with the Earth at the centre required larger epicycles to 'take out' the Earth's motion round the Sun. In other words in the Ptolemaic model the Sun's orbit was the 'reverse' of the Earth's orbit. To that extent the Copernican theory was simpler.

Kepler's theory of 1609 did away with all the old circles and replaced them all with elliptical orbits for the planets, each one in its own plane, close to the ecliptic. He retained the idea that the Sun is at the centre, and devised the Three Laws of planetary motion.

After a full dynamical theory was produced by Newton that explained the elliptical orbits and Kepler's Laws, more and more people accepted that it was right, and that is the situation today, with tiny corrections due to Einstein's General Theory of Relativity.

I am pretty sure that the public disagreed with him when he suggested that the Earth spun on its own axis every 24 hours because the public thought that if it spun that fast everything will blow away with the force of the extreme wind but that didn't happen obviously cause they didn't know about atmosphere.

I am pretty sure this question is right so don't have a go at me if it isn't, but you should check other websites and I think it's right cause in school we are doing and whole topic about the Heliocentric System which Copernicus came up with.

Hope it helped.

pisti ka yawa animal!!

you have been trolled! xD

Because it was the old catholic churches teachings.

because the people would never know and this history about planet would never exist

Everyone just knew that the world was flat... If that was wrong, what else could be wrong...

While many say it was capernicus I think it was actually " Aristarchus" a couple hundred years before Capernicus.

The heliocentric theory is the idea that planets rotate around the sun, where the geocentric theory said that everything orbited around Earth.

HE was the first astronomer to figure out the earth wasn't the center of the universe the sin was it was the heliocentric theory

yes he is

A geocentric theory is one that states the universe is centered by Earth. Geo means earth. The old Ptolemaic Model of the universe has earth as the center.

A heliocentric theory is one that is centered by a source of heat. Helio = heat. It basically states that the sun is the center of our galaxy. (Copernican Model)
