Copernicus mistakenly thought that our earth was the center of our universe, with the sun and other planets orbiting earth.

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.
Before Copernicus , everyone thought the Earth was the centre of the universe. This system was known as the Geocentric system (Earth centred). Copernicus discovered by stellar observation that the Earth was not the centre of the universe. He stated that the Sun was the centre of system of planets, of which the Earth part of that system. At the time of his discovery, the known planets were Mercury, Venus, Earth, Mars, Jupiter and Saturn. Uranus, Neptune and Pluto had not been discovered. The Copernean system is known as the Heliocentric System (Sun Centred).
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.

Nicolaus Copernicus
Nicolaus Copernicus was the astronomer to challenge the geocentric model of the solar system.
Nicolaus Copernicus
The heliocentric model was devised by Copernicus.
true
Copernicus proposed it, Galileo fought for it. It is called the Heliocentric model.
