Sun is center of solar system!
Copernicus was the first to propose the Heliocentric theory, the correct theory that the Sun, not the Earth, is the center of the solar system.
The heliocentric theory was first published by Copernicus.
he developed a theory that the Sun was at the center of the solar system, not Earth
The theory of Copernicus was revolutionary because at the time, people believed the Earth was the center of the solar system instead of the Sun.
Ptolemy thought the earth was the center of the solar system (Otherwise known as the Geocentric theory) and Copernicus's idea was that the sun was at the center of the solar system (Heliocentric theroy).

Sounds like you are looking for Copernicus's theory, which was that the sun was the center of the solar system rather than the Earth.

As proposed by the Heliocentric Theory, the Sun is the center of the Solar System.
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.
The Heliocentric picture of the solar system is a model because it was given as a theory by Copernicus to describe the solar system. In prior centuries people believed that the earth was the center of the solar system.
