Copernicus (Nicolaus Copernicus)

Nicolaus Copernicus was a Renaissance-era astronomer who proposed a groundbreaking model of the universe. He suggested that Earth and other planets orbit the Sun, challenging the long-held view that Earth was the universe's center. His heliocentric theory shifted our understanding of cosmic arrangements, laying the foundation for modern astronomy. Copernicus’s ideas were published in his 1543 book, *De revolutionibus orbium coelestium*, sparking scientific revolution and changing how humanity perceives its place in the universe.
