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.

The sun, does not orbit anything. Because it is the center of the universe, based off of the heliocentric model. Planets, and satelites(moons) do orbit the sun though.

The heliocentric model was devised by Copernicus.

Helio: sun.

Centric: center.

Ergo, heliocentric means "sun-center." If you are talking about orbits, this means that a star (or in our case, the sun) is the center of the orbit.
