He revolutionized astronomy with his ideas about the heliocentric universe, he also published a book about the orbits of the planets and his ideas about the heliocentric universe
In 1543, Copernicus published a book about a new idea he had. Most pople in his day thought that the Earth was the centre of the Universe. But, Copernicus disagreed. according to him, the Universe is not centred around the Earth, but the Earthis actually a planet circling the Sun.
Kepler's theory eventually replaced Copernicus's theory after Tycho Brahe's measurements enabled Kepler to realise that the planets move in elliptical orbits and not in the circles and epicycles of the older Ptolemaic and Copernican models. Copernicus was able to simplify the older model by placing the Sun at the centre instead of the Earth. Kepler in his new theory of 1609 retained Copernicus's idea of placing the Sun at the centre.
Copernicus came up with a new theory of the planets' movements among the stars in 1543. It had the Sun at the centre instead of the Earth, which was in the centre in the ancient Ptolemaic theory. Both theories used circles and epicycles to describe the planet's orbits, which they modelled quite accurately. Copernicus's theory was promoted by Galileo. The modern theory retains Copernicus's idea of placing the Sun at the centre, but it uses elliptical orbits for the planets and was devised by Kepler (1609) working with the latest observations by Tycho Brahe.
Galileo's observations through his telescope, such as the phases of Venus and the moons of Jupiter, provided evidence for the heliocentric model proposed by Copernicus. These discoveries supported the idea that Earth was not the center of the universe and that there were other celestial bodies orbiting around the Sun.
Kepler completely replaced Copernicus's theory of the orbits of the planets, which was based on circles an epicycles, with a new theory using elliptical orbits. However Kepler retained Copernicus's idea of placing the Sun at the centre.

It refers to Copernicus's idea of reconsidering the theory of the universe. Before him, no-one had thought to challenge the accepted ideas. Copernicus's theory was not totally right but he gave the lead to others and eventually a new theory was thrashed out that has been confirmed by later discoveries.

Claudius Ptolemy wrote the first book of astronomy
From about 1510-1514 Copernicus developed his first general outline of his new heliocentric system.
Nicolaus Copernicus's scientific ideas regarding the universe and specifically the idea of heliocentrism were at odds with the generally accepted ideas of his time. It was difficult for people to accept these new ideas, made even more difficult by the Catholic Church's powerful opposition to them for some time.
Copernicus devised a new model of the planets' movements among the stars. To do this he made modifications to the ancient Ptolemaic system. Copernicus considered that the ancient model was geometrically complicated and that it could be simplified very much by placing the Sun at the centre, instead of the Earth. This was controversial because the Ptolemaic model had been around for well over 1000 years and had been incorporated into the scriptures, and it was believed the Earth is at the centre. Not only was it believed but it was also religious dogma. In the end Kepler came up with a new model of elliptical orbits that was shown to be right many years later after the law of gravity and the laws of motion had been discovered. Kepler's theory is the one that is still in use today. Kepler's theory retained Copernicus's idea of placing the Sun at the centre, so Copernicus was proved right in the end, although during Copernicus's lifetime he had no way of knowing it.
That Earth went around the sun.
