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.
What accurately describes the relationship between nicolaus Copernicus and galilei apex?
he provided observational something
Why were Copernicus' ideas about the order of the universe deemed to be dangerous to Church thinking?
The church taught that man was the center of the universe and all things evolved around man. Copernicus stated that earth/man was not the center of the universe and the sun was the center. The church saw this as heresy and that it took power from them because they had made themselves the connection between man and God. Since God was the ruler of the universe and determined all of what man saw and did the science of Copernicus was heresy.
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.
What relationship between the Sun and Earth did Copernicus formulate?
Copernicus changed the accepted heirarchy in the universe by producing a new model of the planets' movements among the fixed stars, as they were called. The accepted model by Ptolemy, who lived in the Roman Empire, had the Earth at the centre of everything, with the Moon, Sun and everything else orbiting round it. The old model used circles and epicycles to explain the planets' orbits round the Earth (an epicycle is a small circle whose centre moves round a larger circle). Copernicus devised an alternative model with the Sun at the centre instead, with the planets including Earth in orbit around it. He found that the new model required smaller epicycles, much small for Mercury, Venus and Mars, and this made him think it was preferable because the orbits were much closer to a simple circular shape instead of the complicated paths of the Ptolemaic system. Copernicus did not publish the new model until the year he died, 1543, because he knew it was contrary to current religious teaching and he had no way of finding which model was more correct because both models represented the planets' movements reasonably accurately. But his work encouraged other scientists who came after him to study the problem, and the model that finally gained acceptance was Kepler's model, published in 1609, which did away with the old circles and epicycles and used elliptical orbits instead. Kepler retained the idea of putting the Sun at the centre and this model was later accepted after it was explained by the laws of motion and the law of gravity.
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.
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.
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 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.

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.
Where was the sun in Ptolemy's model?
Ptolemy calculated the Sun to be the 4th object from the Earth, in between Venus and Mars.

What was the relationship between Nicolaus Copernicus and Galileo Galilei?
Galileo was born 19 years after Copernicus died.
What is the link between Cleopatra VII and Alexander the Great?
The link between Cleopatra and Alexander goes back to the founder of her dynasty, Ptolemy I Sotor. This Ptolemy was a general of Alexander who eventually took over Egypt.
