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.
Aristotle did not believe that the Sun was at the center; he thought Earth was. Aristarchus, a Greek astronomer, is probably the earliest person we know of who supported a heliocentric solar system.
Ptolemy was the first person to introduce the theory of a geocentric universe, a universe in which everything revolves around the earth itself. But in 1543, Nicolas Copernicus was the first person to introduce and prove the idea that the universe is heliocentric, a universe in which everything revolves around the sun.
The first person to promote the idea of the Heliocentric theory was Philolaus, a Pythagorean philosopher. The first "scientist" was Nicolaus Copernicus. He used his teacher's, Tycho Brahe precise measurements to help formulate how the stars moved in the sky and found that the sun moved much faster relative to everything else. He then explained away the movement by applying the Sun as the center of our solar system.

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.

Nicolaus Copernicus was the first astronomer to formulate a scientifically-based heliocentric cosmology that displaced the Earth from the center of the universe. So yes I guess you can say he was a scientist.
Nicolaus Copernicus, a Polish mathematician and astronomer, was the first scholar in the 16th century to propose the heliocentric theory in his book "De revolutionibus orbium coelestium" published in 1543.

Copernicus
Democritus, the ancient Greek philosopher, was the first scientist to propose the concept of atoms as the smallest particle in the universe. He believed that all matter was made up of indivisible and indestructible particles called atoms.
Aristotle did not believe that the Sun was at the center; he thought Earth was. Aristarchus, a Greek astronomer, is probably the earliest person we know of who supported a heliocentric solar system.
Ancient Greek philosopher Aristarchus of Samos is the first known individual to propose that the Sun is at the center of the solar system. His heliocentric model challenged the prevailing geocentric view of the universe.
