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.

Geocentric theory
The heliocentric theory is the idea that planets rotate around the sun, where the geocentric theory said that everything orbited around Earth.
Heliocentric = The Sun is at the center of our solar system. Geocentric = The Earth is at the center of our solar system. Insisting the Sun is at the center, which it is, once very much angered the church.
They both explained which body is in the center of the solar system
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.
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.

Nicolaus Copernicus challenged the geocentric theory and presented the heliocentric theory. The heliocentric system placed the sun at the center of the universe.

The Geocentric Theory states that the Earth is the center of the universe, and that all other objects orbit around it. The Heliocentric Theory states that the Sun is the center of the universe, and all other objects orbit around it. Of course, the Heliocentric Theory is correct, since all astronomical objects orbit around the Sun.
Geocentric theory was the first explanation of the solar system that completely explained and predicted the apparent motions of the planets. The church also embraced this theory and defended it against the heliocentric theory.
