Copernicus discovered the heliocentric theory in 1510 and worked on it for four more years.
copernicus coined the heliocentric theory...
The theory of Copernicus was revolutionary because at the time, people believed the Earth was the center of the solar system instead of the Sun.
Nicolas Copernicus
The discovery did not support Copernicus's theory directly but it raised doubts about the ancient theory of Ptolemy that said that all objects in the sky are in orbit round the Earth. Galileo was an aggressive supporter of Copernicus's theory but eventually it was Kepler's theory that became accepted and is still used today. Both Copernicus and Kepler placed the Sun at the centre but Kepler's elliptical orbits are supported by the later theory of dynamics.
Copernicus' theory was that Earth is not the center of the universe and we revolve around the Sun.
Nicolaus Copernicus
Galelei derived his theory from Copernicus. To Copernicus it was just a theory. Galilei managed to prove it when he invented the telescope and was able to see the moons orbiting Jupiter.
Nicolaus Copernicus disagreed with his theory, Copernicus belived that Ptolemy's view was to complicated.
Copernicus was the first to propose the Heliocentric theory, the correct theory that the Sun, not the Earth, is the center of the solar system.
