Kepler completely replaced Copernicus's theory of the orbits of the planets, which was based on circles an epicycles, with a new theory using elliptical orbits. However Kepler retained Copernicus's idea of placing the Sun at the centre.

Kepler used Tycho Brahe's data to establish the heliocentric theory of the solar system.

Aristarchus of Samos
Galileo did not have his own theory. He was a supporter of Copernicus's heliocentric theory and an opponent of the geocentric Ptolemaic theory. Eventually both theories were rejected in favour of Kepler's theory. But Kepler's theory uses the heliocentric idea from Copernicus's theory.
Tycho Brahe was a nobleman and a difficult character, and it would have been beneath his dignity to 'work together' with Kepler, one of his employees. Most of Kepler's work was done after Brahe's death when he gained access to the figures from Brahe's detailed high-quality measurements. Kepler used the measurements and assumed the heliocentric idea - the Sun at the centre - to produce his three laws of planetary motion. Many years later Newton's discoveries of the laws of motion and the law of gravity, plus his use of differential calculus, showed why Kepler's laws are as they are, and the heliocentric theory was later generally accepted.
Copernicus and later Galileo and Kepler. Venus was found to have phases Jupiter was found to have moons Elliptical orbits which Kepler found would later be described by gravity Start there.
The heliocentric 'theory' is not really a theory at all, more an assertion that the Sun is at the centre of the solar system. Copernicus's theory assumes that the Sun is at the centre and provides a model of the planets' orbits that uses circles and epicycles to explain the observed orbits. He said it was simpler than the old "geocentric" (Earth centred) Ptolemaic system, but it was not really, it actually had more epicycles. Note: Perhaps the questioner got mixed up. The Copernican theory IS a heliocentric theory. Perhaps the question is about the geocentric theory and the Copernican theory. Anyway, Kepler simplified the heliocentric theory and now we know that his model is correct.
copernicus coined the heliocentric theory...
Johannes Kepler, a German scientist, provided the mathematical framework and evidence to support Copernicus' heliocentric theory. Kepler's laws of planetary motion helped confirm that the Earth and other planets revolve around the sun.
The heliocentric theory is the theory that the sun is the center of the universe, not the earth.
