Nicolaus Copernicus
The above answer is incorrect. Copernicus only proved what Aristarchus already discovered, however at that time people rejected his theory since Aristotle was more popular in terms of science than he was.
"He presented the first known heliocentric model of the solar system, placing the Sun, not the Earth, at the center of the known universe...The heliocentric theory was successfully revived nearly 1800 years later by Copernicus"
Aristarchus is the correct answer
Cosmology is the study of the universe as a whole (as compared to our particular corner of the universe, the planet Earth, which we naturally have studied very closely). Cosmology is concerned with such questions as, how was the universe created and what is its past history, how big is it, what does it contain, how does it evolve, what will it be like in the future.
Nicolaus Copernicus was born in the Kingdom of Poland on February 19, 1473. He was the first to formulate a comprehensive Heliocentric Cosmology , which displaced the Earth from the center of the universe. He died on May 24, 1543 in the Kingdom of Poland.
Geocentric: Earth is center of the solar system. Heliocentric: Sun is the centre of the solar system.
Copernicus
Aristarchus's heliocentric model was not accepted by the scientific community because it contradicted the prevailing geocentric view supported by influential figures like Aristotle and Ptolemy. Additionally, the lack of evidence and technology at the time made it difficult to prove the heliocentric model's validity.

Nicolaus Copernicus The above answer is incorrect. Copernicus only proved what Aristarchus already discovered, however at that time people rejected his theory since Aristotle was more popular in terms of science than he was. "He presented the first known heliocentric model of the solar system, placing the Sun, not the Earth, at the center of the known universe...The heliocentric theory was successfully revived nearly 1800 years later by Copernicus" Aristarchus is the correct answer
He was the first astromoner to formulate a comprehensive heliocentric cosmology which displaced the earth from the center of the universe.
Copernicus discovered the heliocentric theory in 1510 and worked on it for four more years.
The theory of cosmology that Copernicus proposed is called the heliocentric theory. This theory placed the Sun, rather than the Earth, at the center of the solar system, with the planets orbiting around it.
Nicolaus Copernicus (February 19, 1473 - May 24, 1543) was the first astronomer to formulate a comprehensive heliocentric cosmology, which displaced the Earth from the center of the universe.
I think this is called the Heliocentric Theory and was first discovered by Copernicus.
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.
He was the first astronomer to formulate a scientifically-based heliocentric cosmology that displaced the Earth from the center of the universe.
Aristarchus discovered that the Earth is a sphere and that the sun is in the center.
Copernicus was credited with being the first astronomer to create a scientific-based heliocentric cosmology that showed the Earth from the center of the universe. He was the starting point of modern astronomy. (From wikipedia)
The heliocentric theory, which placed the Sun at the center of the universe instead of Earth, contradicted the geocentric view endorsed by the Catholic Church. This challenge to the Church's teachings on cosmology was seen as undermining their authority and control over knowledge, leading to conflicts and condemnations against proponents of the heliocentric theory like Galileo Galilei.
