The heliocentric model.
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.
Copernicus proposed a heliocentric model with the sun at the center of the solar system, while Galileo supported this idea with observational evidence through his use of the telescope. Galileo's observations also challenged the geocentric model supported by the Catholic Church at the time.
Galileo, Copernicus, and Ptolemy were key figures in the history of astronomy, each contributing to our understanding of the universe. Ptolemy, in the 2nd century, proposed the geocentric model, placing Earth at the center of the universe, which dominated for centuries. In the 16th century, Copernicus challenged this view with his heliocentric model, suggesting that the sun is at the center, revolutionizing astronomical thought. Galileo, in the early 17th century, supported Copernicus's theory through his telescopic observations, ultimately facing opposition from the Church for advocating this shift away from the geocentric perspective.

The sun-centered universe model is known as the heliocentric model, with the Sun as the center around which the planets orbit. This model was proposed by Nicolaus Copernicus in the 16th century, challenging the prevailing geocentric model that placed Earth at the center of the universe.
Copernicus proposed it, Galileo fought for it. It is called the Heliocentric model.
The earth-centered model created by Ptolemy is called the Ptolemaic model or geocentric model. It proposed that the Earth was the center of the universe, with all celestial bodies moving around it in circular orbits.
Nicolaus Copernicus
The Earth-centered solar system was thought to be sun-centered in the 16th century by astronomers such as Nicolaus Copernicus. Copernicus published his model in 1543, proposing that the Sun, not the Earth, was the center of the solar system. This heliocentric model eventually gained acceptance over the previously held geocentric model.
The Sun-centered or heliocentric model of the solar system is called the Copernican model (after Copernicus) and more closely matches the modern astronomical notions. By contrast, the geocentric or Earth-centric model is often called the Ptolemaic.
