What were the similarities between Ptolemy's model and Copernicus' model?
Wiki User
∙ 8y ago
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.

∙ 8y agoThe planetary models of Ptolemy and Copernicus both used a circular orbit with a combination of epicycles to describe the path taken by each planet. Both models used 40-50 epicycles in the complete model.
The major difference was that Ptolemy had the Earth at the centre in line with the thinking in ancient Greece, while Copernicus placed the Sun at the centre. He found that this simplified the paths followed by the planets.
After Copernicus it took at least another 150 years to sort out the theory of the planets that we use today.

ptolemy theory is a geocentric theory while copernicus theory is a heliocentric theory.

Who contradicted Ptolemys geocentric model?
The heliocentric model proposed by Nicolaus Copernicus contradicted Ptolemy's geocentric model. Copernicus suggested that the Sun, rather than the Earth, was at the center of the solar system.
Who developed ideas that contradicted Ptolemys geocentric model of the universe?
Scientists such as Nicolaus Copernicus and Galileo Galilei developed ideas that contradicted Ptolemy's geocentric model of the universe. Copernicus proposed a heliocentric model with the sun at the center, while Galileo's observations through a telescope supported this idea, leading to the eventual acceptance of the heliocentric model.
What are the similarities beween Copernicus' model of the universe and Ptolemy's model of the universe?
Both Copernicus' and Ptolemy's models aimed to explain the motion of celestial bodies in the sky. However, Copernicus placed the Sun at the center of the universe, while Ptolemy's model had Earth at the center. Both models used the concept of epicycles to explain the retrograde motion of planets.
What was foundation of Ptolemys geocentric model of the universe?
Earth was the center of the universe
What is the similarities between a map and model?
The similarities between a map and model is they both represent something real and they both help you understand something.

Why did the existence of stellar parallax not convince people in Copernicus time that his model was better than Ptolemys geopcentric model?
In Copernicus's time, the lack of perceived stellar parallax was not considered strong evidence because people believed that the stars were too distant for their motion to be detected. Additionally, many were entrenched in the geocentric model due to longstanding tradition, religious beliefs, and lack of understanding of heliocentric principles. It took further advancements in observational technology and understanding of astronomy for the heliocentric model to gain widespread acceptance.

How was Copernicus model of the universe different from ptolemys model?
Copernicus's model thought that the planets orbited the sun. Ptolemy's model thought that the planets orbited the moon.No. The above answer is incorrect.Copernicus's model thought that the planets orbited the sun. Ptolemy's model thought that the planets orbited the EARTH in epicycles. Not the moon. (The model that modeled the planets orbiting earth was the Geocentric model. Aristotle theorized this.)Copernicus's model is known as the Heliocentric model. Ptolemy's theory of epicycles is when the planets revolved in large circles around Earth.
What was foundation of Ptolemys geocentric model of the universe?
Earth was the center of the universe

How did Copernicus realize that Venus is an inferior planet?
it was know in ancient times that Venus passes between the Earth and the Sun, and Copernicus had a model which had the Sun at the centre, so in his model Venus was closer to the centre, thus an inferior planet by definition.
When did Copernicus realize that Venus is an inferior planet?
it was know in ancient times that Venus passes between the Earth and the Sun, and Copernicus had a model which had the Sun at the centre, so in his model Venus was closer to the centre, thus an inferior planet by definition. That was in about 1560.
What made Copernicus realize that Venus is an inferior planet?
