Nicolaus Copernicus proposed a heliocentric model of the solar system, which deviated from the geocentric model in the Ptolemaic system. In Copernicus' model, the Sun, not Earth, was at the center of the universe, with the planets, including Earth, revolving around it.
Copernicus and Galileo were two major figures whose ideas contradicted Ptolemy's geocentric model. Copernicus proposed a heliocentric model with the Sun at the center of the solar system, while Galileo used observations through a telescope to support this view and challenge Ptolemaic beliefs.
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.
Copernicus' model gained support because it provided a simpler explanation for celestial phenomena compared to the Ptolemaic model. The heliocentric system was more elegant and accurately predicted the movements of the planets. Additionally, observations made with the invention of the telescope provided further evidence in support of Copernicus' model.
That is correct. The sun is at the center of our solar system, and all the planets, including Earth, orbit around it due to its gravitational pull. This model is known as the heliocentric system, proposed by Copernicus in the 16th century.

Nicolaus Copernicus proposed a heliocentric model of the solar system, which deviated from the geocentric model in the Ptolemaic system. In Copernicus' model, the Sun, not Earth, was at the center of the universe, with the planets, including Earth, revolving around it.
He placed the Sun in the middle of the Solar System, instead of the original format where the Sun, Earth, and moon were all in the middle.

The Ptolemaic system placed Earth at the center of the universe, with other celestial bodies orbiting around it, while the Heliocentric system, proposed by Copernicus, placed the Sun at the center with planets, including Earth, orbiting around it. The Ptolemaic system was geocentric, while the Heliocentric system was heliocentric.
The main idea in the Ptolemaic system was that the Earth was at the center of the universe, with the Moon, Sun, planets, and stars orbiting around it in perfect circles. This geocentric model dominated Western astronomy until it was eventually replaced by the heliocentric model proposed by Copernicus.

The Ptolemaic theory is an ancient geocentric model of the universe that posited Earth as the center of the universe with other celestial bodies moving around it. It was developed by the astronomer Ptolemy in the 2nd century AD and was widely accepted until the heliocentric model proposed by Copernicus in the 16th century.
Copernicus published an alternative model of the planets' movement in 1543 that had the Sun at the centre. It was the first heliocentric model. It used orbits based on combinations of circles, as the ancient Ptolemaic system had done, which was geocentric. In Copernicus's model the paths followed by the planets were less complicated, but other than that Copernicus had no way of proving if it was right or not at that time, so it isn't known whether he believed in it.

Copernicus used perfect circles for the orbits of the planets.
