heliocentric model:
A model with the Sun at the centre and the Earth going round. It was just another theory until dynamical theories came along in the 18th/19th century that showed it is a much better theory than the other ones because the Sun is 300,000 times more massive than the Earth. After that everyone adopted this theory as the true situation.
Nicolaus Copernicus, after whom the Copernical model is named, advanced the idea of the heliocentrism in the middle 16th century, which is often regarded as the starting point for modern astronomy. There were earlier thinkers whose work did not survive or was not broadly accepted, such as Aristarchus of Samos who may have been first to seriously propose the Sun was at the solar system's center around the third century BC.

earth
Nicolaus Copernicus proposed that the Sun, not the Earth, was the center of the solar system and that the planets, including Earth, revolved around the Sun in circular orbits. This heliocentric model challenged the prevailing geocentric view of the time.
Nicolaus Copernicus!
heliocentric 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.
This was actually known to the ancient Greeks. In more modern times, Copernicus is credited with this idea.
Copernicus was not the first to propose a sun centered Solar System. He cited the ideas of ancient Greek thinkers Philolaus and Aristarchus of Samos as an influence.
When did Copernicus write his book on the solar system?
