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.
He thought of and supported the heliocentric model, which states the "heavens" revolve around the Sun.
The Geocentric or Ptolemaic Model put the earth at the center of the Universe. The Heliocentric Model postulated by Copernicus and, before him, Aristarchus, places the Sun at the center of the Solar System. Galileo's observations proved the validity of the Heliocentric Model.
copernicus coined the heliocentric theory...
Copernicus discovered the heliocentric theory in 1510 and worked on it for four more years.
He believed in a heliocentric universe, or a universe where all of the planets revolve around the sun.
He is worth knowing about because he revived the Heliocentric modelSome say that he reveled the Heliocentric model but he didn'tBut he was the first person to try to push people to to believe in the Heliocentric model

Copernicus proposed the theory of a heliocentric model while Galileo improved the telescope, studied Jupiter's moons, and supported the heliocentric model
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.
Copernicus' heliocentric model provided the framework for Galileo to further explore and confirm through his observations with the telescope. Galileo's discoveries, such as the moons of Jupiter and the phases of Venus, provided empirical evidence in support of the heliocentric model and contributed to its acceptance over the geocentric model.
The heliocentric model was devised by Copernicus.
