Copernican Heliocentrism

COPERNICAN HELIOCENTRISM

NICOLAUS COPERNICUS was a Renaissance-era mathematician and astronomer who formulated a model of the universe that placed the Sun rather than the Earth at the center of the universe. He wrote a book entitled De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres). It is the seminal work on the heliocentric theory. This book offered an alternative model of the universe to Ptolemy's geocentric system, which had been widely accepted since ancient times.

HELIOCENTRIC SYSTEM  The word “helious” in Greek mean “Sun”  A Heliocentric system is one in which the planets revolved around a fixed sun.  Copernican heliocentrism is the name given to the astronomical model developed by Nicolaus Copernicus and published in 1543. It positioned the Sun near the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths modified by epicycles and at uniform speeds.

CONTRIBUTION IN THE MODERN WORLD  The Copernican Heliocentric formed a strong foundation for future scientists to build on and improve mankind's understanding of the motion of heavenly bodies.

 Other astronomers built on Copernicus' work and proved that our planet is just one world orbiting one star in a vast cosmos loaded with both, and that we're far from the center of anything.

ARE NICOLAUS COPERNICUS'S ACHIEVEMENTS STILL FELT TODAY? • Nicolaus Copernicus is heavily cited as the father of modern astronomy and is the reason why we know this much about space now. Although he wasn't the one to persuade other scientists about the heliocentric theory, he was the one to start it all, the one who would set the scientific world up for nearly six hundred years later in the future.
