Copernicus's system used circles and epicycles, just like the ancient Ptolemaic system, with the difference that by placing the Sun at the centre Copernicus could simplify the complicated paths taken by the planets through space.
Kepler had the advantage of new accurate observations made by Tycho Brahe at the end of the 16th century, and these enabled Kepler to realise that by using elliptical orbits for the planets, the modelled positions could be fitted more closely with the measured positions.
Kepler retained the idea of having the Sun at the centre and it is the model used today with slight modifications from Einstein's theory of relativity.

What is the main difference between Kepler's system and Copernicus system?
The main difference between Kepler's system and Copernicus' system lies in their approach to planetary motion. Copernicus proposed a heliocentric model, where the Sun is at the center of the solar system, while Kepler's model focused on the elliptical orbits of planets around the Sun. Copernicus' system laid the groundwork for a sun-centered model, while Kepler's laws of planetary motion provided a more accurate description of the paths planets take as they orbit the Sun.
What is the difference between a system of numerals and a set of numbers?
there is a huge difference. :)
