the father of Modern Astronomy, a Mathematician, Astronomer, Catholic priest that was born in Krakow, Poland on February 19, 1473 and died on May 24, 1543.

Prior to the publication of his major astronomical work, “On the Revolutions of the Heavenly Spheres,” in 1543, European astronomers argued that Earth lay at the center of the universe, the view also held by most ancient philosophers.

In addition to correctly postulating the order of the known planets from the sun and estimating their orbital periods relatively accurately, Copernicus argued that Earth turned daily on its axis and that gradual shifts of this axis accounted for the changing seasons.

Sometime between 1509 and 1514, Copernicus wrote a short astronomical treatise commonly called the Commentariolus, or “Little Commentary,” which laid the basis for his sun- centered or heliocentric theory, a radical departure from the conventional wisdom of his era. The work was not published in his lifetime.

Copernicus delayed publication of his major astronomical work, De revolutionibus orbium coelestium libri vee or “On the Revolutions of the Heavenly Spheres,” nearly all his life. Completed around fifteen thirty it was not published until fifteen forty three — the year of his death.

The theory states that the Earth was a planet like Venus or Saturn, and that all planets circled the sun.

Copernican theory gathered few followers and for a time, some of those who did give credence to the idea faced charges of heresy.

There was this one Italian Scientist named Giordano Bruno that was burned at the stake for teaching Copernicus' view of the universe or the Heliocentric View of the Universe or Heliocentrism

Yet, there is this one major flaw in his theory. We all know that the sun is only the centre of the solar system and not the whole universe.
