He had a theory that the earth revolved around the sun. Hundreds of years later, scientists proved he was right. Back then, everybody believed Aristotle and they thought the earth was at the center of the universe and everything revolved around it. Galileo kind of based his theory on that too, but it was Copernicus who thought of it.

Copernicus was the first scientist to postulate that our solar system was heliocentric. Until that time, everyone "knew" that the earth was the center of the solar system - everything else, including the sun, revolved around the earth. Copernicus got considerable grief for his views, and it was several more centuries before it was universally accepted that he was correct - the solar system is heliocentric.

Nicolaus Copernicus
Nickolaus Swedlund's birth name is Nickolaus William Swedlund.
Nicolaus Copernicus came up with the theory that the Sun is the center of the Universe and not the Earth, contrary to the popular belief then. This made him famous.
Galelei derived his theory from Copernicus. To Copernicus it was just a theory. Galilei managed to prove it when he invented the telescope and was able to see the moons orbiting Jupiter.
Nicholas Copernicus is famous for his heliocentric theory of the solar system, which proposed that the Earth and other planets revolve around the Sun. This theory revolutionized the understanding of the universe and challenged the prevailing geocentric model. Copernicus's work laid the foundation for modern astronomy and had a profound impact on scientific thought.
