The answer lies in the question.
It is called "The Heliocentric Theory" for a reason. But don't let yourself be confused by that.
There is a common misconception that the good Theories in science grow up to become Laws, when that simply isn't true. In everyday vernacular, "Theory" is described as a postulated guess. In science, it is quite different.
A Law describes what nature does under certain conditions, and predicts what will happen as long as those conditions are met.
A theory, on the other hand, explains how nature works.
Indeed, one only needs to recognize that it is a fact that the earth orbits the sun, then look at what that principle is called (A "theory") to realize that "Theories" have a lot more going for them than people think.
copernicus coined the heliocentric theory...
The heliocentric theory is the theory that the sun is the center of the universe, not the earth.

Galileo did not propose a heliocentric theory, he agreed with Copernicus and his heliocentric theory. The Catholic church, at the time, disagreed and they held a huge amount of power and put him on trial.
Copernicus discovered the heliocentric theory in 1510 and worked on it for four more years.
He was a Polish mathematician who disagreed with Ptolemy's view that the earth is the center of the universe. The heliocentric theory is the theory that the sun is the center of the universe, not the earth.
The heliocentric theory is the idea that planets rotate around the sun, where the geocentric theory said that everything orbited around Earth.
He was a Polish mathematician who disagreed with Ptolemy's view that the earth is the center of the universe. The heliocentric theory is the theory that the sun is the center of the universe, not the earth.
heliocentric theory
If you mean what scientist created the heliocentric theory, it was Nicolaus Copernicus. Based on astronomical observations, he determined that the Ptolemaic geocentric theory was incorrect, and replaced it with his own heliocentric theory, which placed the sun at the center of the universe, and had planets orbiting the sun.
