What was not a major advantage of Copernicus' Sun-centered model over the Ptolemaic model?
It made significantly better predictions of planetary positions in our sky.
What did Copernicus believe the planetary motions were due to?
3r
How did Kepler expand on Copernicus' ideas?
Kepler showed that planetary orbits were actually ellipses, not circles as proposed by Copernicus.
Concerning the planetary orbits why was Copernicus somewhat inaccurate?
He suggested the orbits were circles.
How did Copernicus disprove geocentricism?
Copernicus didn't disprove goecentrism, that was done by Johannes Kepler, who wrote his 3 Laws of Planetary Motion. These were then expanded on by Newton to justify his theory of Gravitation.
What was not a major advantage of Copernicus' Sun-centered model over the Ptolemaic model?
It made significantly better predictions of planetary positions in our sky.
Copernicus' model of the solar system gave much better predictions than the model of Ptolemy?
Yes, Copernicus' heliocentric model of the solar system, with the Sun at the center, provided more accurate predictions of planetary movements compared to Ptolemy's geocentric model, which had the Earth at the center. This was due to the simplicity and elegance of Copernicus' model, leading to a better understanding of the true nature of the solar system.
System an early geocentric theory planetary motion?
ptolemaic
What was Copernicus objection to ptolemaic system?
Copernicus objected to the Ptolemaic system primarily due to its complexity and reliance on epicycles to explain planetary motions. He believed that the geocentric model, which placed Earth at the center of the universe, was unnecessarily convoluted. Instead, Copernicus proposed a heliocentric model, positioning the Sun at the center, which provided a simpler and more coherent explanation for the observed movements of celestial bodies. This shift laid the groundwork for modern astronomy by challenging long-held beliefs about the structure of the universe.
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.
Who came up with the planetary model?
COPERNICUS!!
What did Copernicus not reject?
Copernicus did not reject the idea that planetary orbits around our Sun were circular.
What did Copernicus believe the planetary motions were due to?

How did Kepler's findings support Copernicus's theories How did those ideas dispel Ptolemy's theories?
Kepler's findings, particularly his laws of planetary motion, provided strong mathematical support for Copernicus's heliocentric model, demonstrating that planets move in elliptical orbits rather than perfect circles. This contradicted Ptolemy's geocentric model, which relied on complex circular orbits and epicycles to explain planetary movements. By showing that the sun, not the Earth, is at the center of planetary orbits, Kepler's work helped to validate Copernicus's theories and laid the groundwork for modern astronomy, ultimately displacing the Ptolemaic system.
How did Kepler expand on Copernicus' ideas?
Kepler showed that planetary orbits were actually ellipses, not circles as proposed by Copernicus.
Who confirmed copernicus' heliocentric theory?
Aristarchus of Samos
What caused Copernicus to challenge aristotles theories of planetary motion?
Copernicus challenged Aristotle's theories of planetary motion due to observations that didn't align with the geocentric model, particularly the retrograde motion of planets. Through his own observations and mathematical calculations, Copernicus proposed a heliocentric model where the Earth and other planets revolve around the Sun, providing a simpler explanation for the observed phenomena in the sky.
