Copernicus lived from Feb 1473 until 24th May 1543. His book "De revolutionibus orbium coelestium" was published just before his death._______________________However, Copernicus didn't publish the first heliocentric model of the solar system. That was Aristarchus of Samos, a Greek astronomer and mathematician, about 2400 years ago.
Copernicus was the first astronomer to look critically at the accepted model of the planets' movements among the stars, and he published an alternative theory in 1543. His model had the Sun at the centre and he thought it looked good because the geometrical complications in the old Ptolemaic model, that had the Earth at the centre, were simplified. Copernicus's theory was eventually superseded by the later theory of Kepler (1609) which also placed the Sun at the centre. Kepler's model fitted recent measurements of the planets' movements, made by Tycho Brahe, very accurately. Until the late 1600s there was no way to make a definite choice between these theories. But after the theory of gravity and the laws of motion were discovered, they were used to show that Kepler's model fitted the new theories very closely. Although Copernicus's theory ended up being rejected it is of historical interest because he encouraged later astronomers to take up the topic and eventually make significant progress.
Copernicus's theory did not fail but it was not as accurate as the Kepler model because it did not include elliptical orbits for the planets, as Kepler's model did. However the data for calculating the elliptical orbits did not become available until well after Copernicus's death so he had no chance of knowing about this change. Copernicus's model which used circles and epicycles was accurate to the standard of the observations that were available to him.
While Nicolas Copernicus is widely credited with developing the idea of the Sun-centered or "heliocentric" model of the solar system, the original idea was published nearly 2000 years earlier by the Greek astronomer and mathematician Aristarchus of Samos.
Heliocentricism was first proposed by Aristarchus of Samos (circa. 270 BCE), who concluded the Sun was hundreds of thousands of times larger than Earth and was the center of a system in which the Earth revolved around it. His work is largely lost today.In the 16th century, however, Nicholaus Copernicus formulated a heliocentric model of the solar system in which the Sun was at the center. Known as the "Father of Modern Astronomy," Copernicus's work was fundamental in establishing controversial ideas of the Earth revolving around the Sun, and gave substance to Aristarchus's earlier theory. Though Copernicus stirred up controversy, his publication of the book De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), he began what was known as the Copernican Revolution and contributed to the scientific revolution. His book is often considered a major mark in the history of science.
The greatest inaccuracy in Copernicus' model of the solar system was that he still believed that planets moved in perfect circles, when in fact they move in ellipses. This led to inaccuracies in predicting planetary positions.

Nicolaus Copernicus.
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.
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.

Ptolemy proposed a geocentric model, with Earth at the center and planets orbiting it. Copernicus suggested a heliocentric model, with the Sun at the center of the solar system. Galileo's telescopic observations supported the heliocentric model and provided evidence for Copernicus' theory.
Nicolaus Copernicus
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.
The heliocentric model was devised by Copernicus.
Copernicus proposed it, Galileo fought for it. It is called the Heliocentric model.
