Copernicus's heliocentric theory

Mikołaj Kopernik (Nicolaus Copernicus), Polish astronomer, mathematician and translator born in 1473 in Toruń discovered that the Sun is in the centre of the solar system and the planets orbit it. He wrote a book titled 'On the Revolutions of the Celestrial Spheres', where he presented the heliocentric theory of the universe.
