Galileo Galilei noted that; if our Earth and other planets went around our Sun, Venus would exhibit phases like our Moon; but if our Sun and other planets went around our Sun, it wouldn't. GG looked at Venus over the course of several weeks and noted unmistakeable phases. He thus concluded that the Copernican model was not just a useful model for calculation, but supported by observation.

The Heliocentric theory was significant because Copernicus had proved something such a long time ago... the fact that it hasn't been proven wrong, or the fact that no-one else believed him because they didnt have the technology to prove it back then.
Ptolemy thought that the Earth was the center of solar system and most people believed this theory. But Copernicus thought that the Sun was the center of solar system and most people didn't believed this theory. Who was right? Copernicus was right because later Galileo prove that if the Earth was at the center then he couldn't see the phases of Venus. Sentences for heliocentric. Galileo proved that the Copernicus's theory which was heliocentric was right.
Neither, The Geocentric theory was created by a student of 'Plato's' by the name of Ptolemy. The Heliocentric theory was by Copernicus.
Heliocentric theory of universe.

Copernicus discovered the heliocentric theory in 1510 and worked on it for four more years.

Copernicus, with the use of the heliocentric theory and Galileo with his telescope proved the planets revolve around the Sun.
Nicolas Copernicus
heliocentric theory
Nicolaus Copernicus challenged the geocentric theory and presented the heliocentric theory. The heliocentric system placed the sun at the center of the universe.
Copernicus
As proposed by the Heliocentric Theory, the Sun is the center of the Solar System.
