De revolutionibus orbium coelestium

"De revolutionibus orbium coelestium," written by Nicolaus Copernicus in 1543, is a groundbreaking work that proposed a heliocentric model of the solar system, suggesting that the Earth and other planets orbit the Sun. This was a significant departure from the prevailing geocentric model, which placed the Earth at the center. Copernicus’ ideas challenged established beliefs and laid the foundation for modern astronomy, influencing thinkers like Galileo and Kepler. The work marked a pivotal shift in understanding our place in the universe, ultimately leading to the Scientific Revolution and transforming how humanity perceives space and celestial bodies.
