Why was Nicholas Copernicus so interested in space?

Nicholas Copernicus was deeply interested in space primarily due to his pursuit of understanding the cosmos and its mechanics. He sought to explain the apparent retrograde motion of planets and the complex movements of celestial bodies, which led him to challenge the Earth-centered Ptolemaic model. Copernicus's fascination with mathematics and astronomy drove him to develop the heliocentric theory, proposing that the Sun, not the Earth, was at the center of the universe. His work laid the foundation for modern astronomy and shifted humanity's perspective on its place in the universe.
