Aristarchus of Samos was the first person (that we know of!) that proposed a heliocentric model of the universe, as early as about 200B.C). His model was rejected mainly because of Aristotle's influence.
Copernicus was the next person to propose a heliocentric model of the universe which was published in 1547. although very controversial at that time, this model was the one that caught on.
that the world was heliocentric not geocentric aka sun centered universe and earth centered universe
Nicolas Copernicus
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 Geocentric or Ptolemaic Model put the earth at the center of the Universe. The Heliocentric Model postulated by Copernicus and, before him, Aristarchus, places the Sun at the center of the Solar System. Galileo's observations proved the validity of the Heliocentric Model.
Copernicus
The scientist who rejected the heliocentric model of the solar system was Claudius Ptolemy, an ancient Greek astronomer and mathematician. Ptolemy proposed a geocentric model where Earth was at the center of the universe with all other celestial bodies orbiting around it.
Aristarchus of Samos was the Greek scientist who first proposed a heliocentric view of the universe, suggesting that the Earth revolves around the Sun. This idea was revolutionary for its time and laid the foundation for later heliocentric models developed by Copernicus and Galileo.
The geocentric universe was proposed by Ptolemy and focuses the Earth in the center of the universe. The heliocentric universe was proposed by Nicolas Copernicus and focuses the Sun as the center of the universe. However, both have been proved wrong.

Nicolaus Copernicus was the scientist who wrote the book "De Revolutionibus Orbium Coelestium" (On the Revolutions of the Celestial Spheres) in 1543, in which he proposed the heliocentric model of the universe with the sun at the center.
Nicolaus Copernicus, a Polish astronomer, proposed the heliocentric model in the 16th century, suggesting that the Sun is at the center of the universe with the Earth and other planets orbiting around it. This idea challenged the prevailing geocentric model, where Earth was considered the center of the universe.
Aristarchus of Samos
Yes, Voltaire supported the heliocentric view of the universe proposed by Copernicus. He wrote about it in his work "Elements of Newton's Philosophy" where he praised the advancements made by Copernicus, Galileo, and Newton in understanding the cosmos.
The Greek astronomer Claudius Ptolemy believed that Earth was at the center of the universe in his geocentric model, which was widely accepted in the ancient world. This view held sway until the heliocentric model proposed by Copernicus in the 16th century challenged it.
Nicolaus Copernicus showed that our universe is heliocentric.
Tycho Brahe proposed a universe where the Earth was at the center (geocentric model) while other planets revolved around the Sun (heliocentric model). His system was known as the Tychonic system, which attempted to reconcile both models.
The heliocentric model places the Sun at the center of the solar system, with planets orbiting around it. In contrast, the geocentric model positions Earth at the center of the universe, with celestial bodies, including the Sun, revolving around it. The heliocentric model was proposed by astronomers like Copernicus and Galileo and marked a significant shift in understanding the cosmos.
