Retracing Heliocentric Model of Nicolaus Copernicus

Abstract

The Polish Astronomer Nicolaus Copernicus is widely considered, as ‘The father of Modern Astronomy’ for his theory on ‘Heliocentric Model’, of Sun centered theory, which was a radical departure from the then existed theory that the Earth revolves around the Sun. Nicolaus Copernicus earlier published about the Heliocentric System in his famous book: De Revolutionibus Orbium Colelestium, ‘On the revolution of the Heavenly Bodies’. The claim that all planets revolve around the Sun  had been raised in earlier Ancient times ,but Copernicus was the first to achieve in narrating the astounding theoretical thought of movements of the Planets using an Astronomical concept which deals with Sun at the center. So far information goes, his career was in ambiguity. It is learnt that never earned a bachelor degree, although visited a lot of colleges, as well as attended attained several Universities namely Cracow, Bologna, Padua and others. According to him the Earth and Planets revolve around the center that was near the Sun but was not exactly the Sun. His major Astronomical work was “On the Revolution of the Heavenly Spheres in 1543”.His idea was that axis rotates daily on its axis and that axis gradually shifts which is the reason why we observe the changing of seasons. In his time, people bored the idea that Astrology and Astronomy were closely connected. This paper is a brief approach to look back the brilliant contributions of Copernicus retracing ‘Heliocentric Model’.
