Nicolaus CopernicusDied 24 May 1543 at age 70 (born 19 Feb 1473). Polish astronomer who proposed the heliocentric model of the Solar System in which all the planets orbit around the Sun at the centre. He recognizedthat the Earth is a planet which, besides orbiting the Sun annually, also turns once daily on its own axis; and that very slow, long-term changes in the direction of this axis account for the precession of the equinoxes. He understood the immense distance of the stars. He wrote his ideas in a book, De Orbium Coelestium Revolutionibus. Although completed in 1530, he requested it be published after his death in 1543. Until 1758, the Roman Catholic Church banned the book as contrary to religious dogma.« |
