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.
Galileo's support for the heliocentric theory (note that this is Copernicus's theory, not Galileo's) got him into trouble with the Roman Catholic Church. In 1633 the Inquisition convicted him of heresy and forced him to recant (publicly withdraw) his support of Copernicus. They sentenced him to life imprisonment, but because of his advanced age allowed him serve his term under house arrest at his villa in Arcetri outside of Florence.
The Copernican theory challenged the popular notion that the earth was at the center of the solar system, and instead proposed that the Sun was; ("Heliocentric") and indicated that observations of motions of other planets and stars was consistent with the Earth itself being the object that moved.
The Vatican did not believe in heliocentric theory for a long time.
Neither, The Geocentric theory was created by a student of 'Plato's' by the name of Ptolemy. The Heliocentric theory was by Copernicus.
The Geocentric Theory is about how everything revolves and the Earth and the Heliocentric Theory is how everthing revolves around the Sun.
Nicolaus Copernicus
The main difference - is the centre of the galaxy. The heliocentric theory placed the Sun at the centre of our galaxy - the previous 'geocentric' theory placed the Earth at the centre.
Helios is Greek for the Sun, so helio-centric means the Sun is at the centre.
Likes: Created Copernican Theory, proposed heliocentric theory, great astronomer Dislikes: Went against Church's theory, went against Bible's theory, disagreed with geocentric theory.
A geocentric theory is one that states the universe is centered by Earth. Geo means earth. The old Ptolemaic Model of the universe has earth as the center. A heliocentric theory is one that is centered by a source of heat. Helio = heat. It basically states that the sun is the center of our galaxy. (Copernican Model)

The Ptolemaic theory (geocentric) put forth by Claudius Ptolemy (100-170 AD) was based partly on the work of Aristotle. It was replaced by the Copernican theory (heliocentric) beginning around 1400 AD.
copernicus coined the heliocentric theory...
