Actually the ancient Greeks were the first to realize the world was round.
The Polish astronomer who proposed that the Earth revolves around the Sun is Nicolaus Copernicus. His heliocentric theory, presented in his work "De revolutionibus orbium coelestium" in 1543, challenged the long-held geocentric view that placed the Earth at the center of the universe. Copernicus's ideas laid the groundwork for future astronomical discoveries and significantly changed the course of scientific thought.

1500s
Nicolaus Copernicus's theory that the Earth orbits the Sun was shocking to people in the 1500s because it challenged the long-held geocentric view, which placed the Earth at the center of the universe. This belief was deeply rooted in religious and philosophical traditions, including interpretations of biblical scripture. Copernicus's heliocentric model not only contradicted centuries of astronomical observations but also implied that humanity was not the central focus of the cosmos, which unsettled both scientific and religious perspectives of the time.
In the 1500s, Nicolaus Copernicus proposed the heliocentric model of the solar system, which posited that the Sun, rather than the Earth, is at the center of the universe. This revolutionary idea challenged the long-held geocentric view that placed the Earth at the center, fundamentally altering the understanding of celestial mechanics and laying the groundwork for modern astronomy. Copernicus' work, detailed in his book "De revolutionibus orbium coelestium," sparked significant debate and eventually contributed to the Scientific Revolution.
copernicus?
Nicolaus Copernicus.
I am not sure which of his books you are asking us about, since he wrote at least three of them. But his best known was On the Revolutions of the Celestial Spheres (in Latin,De revolutionibus orbium coelestium). Nicolaus Copernicus was an astronomer, and this book taught something entirely new for the 1500s-- that the planets revolved around the sun.
It was Copernicus.

Nicolaus Copernicus proposed the heliocentric model with circular orbits of the planets around the Sun in the 1500s. His work, "De revolutionibus orbium coelestium," laid the foundation for the Copernican Revolution in astronomy.

In the 1500s, Nicolaus Copernicus further developed the heliocentric explanation for the motion of the planets with his publication of "De revolutionibus orbium coelestium" (On the Revolutions of the Celestial Spheres) in 1543. He proposed that the Sun, not Earth, was the center of the solar system.
The first astronomer to dispute the model seriously was Nicholas Copernicus in the 1500s. His model used circles and epicycles, like the old Ptolemaic model, but had the Sun at the centre, which led to its being named the heliocentric model. Sixty years after his death in 1543, the Copernicus model was taken up by Galielo in his dispute with the Catholic church. In the latter half of the 1600s further discoveries led to wider acceptance of the heliocentric concept. However the rest of the Copernicus model was discarded and replaced by Kepler's model which had each planet in an elliptical orbit, and this was taken up and given scientific credibility by the discoveries of Newton and others.
His views went against traditional beliefs, including those of the Roman Catholic Church.
