How were Copernicus' and Kepler's theories about the movement of the planets similar How were they different?
Copernicus started the ball rolling with a new theory explaining how the planets move, using circles and epicycles as Ptolemy had done, but with the Sun assumed to be at the centre. He claimed that the new theory was simpler than Ptolemy's theory, which was later found to be not actually the case. But Copernicus's theory was used to predict the positions of the planets. Later Tycho Brahe found ways of making accurate measurements of the planets' positions, and discovered small errors in predictions that were based on Copernicus's theory. Kepler retained the idea that the Sun is at the centre, but used Tycho's measurements to research a new detailed theory of the planets' orbits. After long and arduous studies he discovered that the orbits are elliptical, and published three laws of planetary motion which were a huge step forward in scientific knowledge. Newton made further discoveries that explained how elliptical orbits are produced by the Sun's gravity. He said he had stood on the shoulders of giants, and Kepler must have been at the front of his mind. Kepler's achievement is enormous because the difference between an ellipse of the type that the planets move in and a circle with the Sun offset from the centre - as predicted by the old theory with epicycles - is extremely small.

Why were Copernicus' ideas about the order of the universe deemed to be dangerous to Church thinking?
Nicolaus Copernicus' heliocentric theory, which proposed that the Sun, not the Earth, was at the center of the universe, was considered dangerous to Church thinking for several key reasons: Contradiction of Scripture: The prevailing belief, supported by the Catholic Church at the time, was the geocentric model (Earth-centered universe), which had been deeply rooted in both ancient Greek thought (like Ptolemy's model) and interpretations of the Bible. Several scriptures, such as passages in the Book of Psalms and Joshua, were traditionally interpreted as suggesting that the Earth was immobile and that celestial bodies, like the Sun, Read more...tinyurl. com/bdh966cc
What is the main difference between Kepler's system and Copernicus system?
The main difference between Kepler's system and Copernicus' system lies in their approach to planetary motion. Copernicus proposed a heliocentric model, where the Sun is at the center of the solar system, while Kepler's model focused on the elliptical orbits of planets around the Sun. Copernicus' system laid the groundwork for a sun-centered model, while Kepler's laws of planetary motion provided a more accurate description of the paths planets take as they orbit the Sun.
What is the main difference between keplers system and the Copernicus system?
Copernicus's system used circles and epicycles, just like the ancient Ptolemaic system, with the difference that by placing the Sun at the centre Copernicus could simplify the complicated paths taken by the planets through space. Kepler had the advantage of new accurate observations made by Tycho Brahe at the end of the 16th century, and these enabled Kepler to realise that by using elliptical orbits for the planets, the modelled positions could be fitted more closely with the measured positions. Kepler retained the idea of having the Sun at the centre and it is the model used today with slight modifications from Einstein's theory of relativity.
How many times did earth orbit the sun between 140 C.E when Ptolemy introduced his theories and 1543 when Copernicus introduced his?
The earth revolved around the sun 1403 times between 140-1543.
How many years are between Ptolemy and Copernicus?
Approximately 1,400 years separate the work of Ptolemy, who lived in the 2nd century AD, and Copernicus, who lived in the 16th century.
According to Copernicus what planet are located between the sun and the earth?
All the theories have Mercury and Venus between the Earth and the Sun.
How are Copernicus theory and Ptolemy theory have in common'?
Both the Copernican and Ptolemaic models were geocentric theories that sought to explain the motion of celestial bodies, particularly the movement of the Sun, Moon, and planets in relation to Earth. However, the key difference between the two theories lies in their proposed structure of the solar system, with Copernicus advocating a heliocentric model (Sun-centered) while Ptolemy supported a geocentric model (Earth-centered).
What were the similarities between Ptolemy's model and Copernicus' model?
Both Copernicus heliocentric and the Ptolemaic models agreed on the need for epicycles. These were miniature orbits that the celestial bodies travelled on as well as their normal orbits.Copernicus still invigaed the bodies orbiting in perfect circles and had to put these in to explain some of the movements of the planets. This may have contributed to his ideas being largely dismissed as it was just as complicated as the already established model. It was not until Kepler proposed elliptical orbits was this problem resolved.

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.
What is the similarity between the Ptolemy and Copernicus models of the solar system?
The similarity is that both theories used a system of circles and epicycles to explain how the planets move around. Copernicus's theory (1543) used a similar number of epicycles, but many of them were smaller so that the paths followed by the planets were geometrically simpler. The difference was that Copernicus placed the Sun at the centre rather than the Earth as the ancient theory had done. Another theory was later produced by Kepler (1609), which used Copernicus's idea of having the Sun at the centre, but Kepler used elliptical orbits for the planets. This new model fitted observational measurements better, but it was not until many years later after the discovery of the law of gravity and the laws of motion (1687) that it was possible to pick out Kepler's theory as the correct one that is still in use today.
What was the relationship between Nicolaus Copernicus and Galileo Galilei?
Galileo was born 19 years after Copernicus died.

What is the difference between the Ptolemy and Copernicus models of the solar system?
The difference between Ptolemy's and Copernicus's model was that, Ptolemy's model had the Earth in the middle of the Solar System, with all the other planets (including the Sun and the moons) revolving around it. In Copernicus's model, he had the Sun in the center of the Solar System.
