About this design
Before Copernicus (who was actually Polish - Mikołaj Kopernik) , the accepted theory was that Earth was the centre of universe. The Planets however seemed to wander all over the sky in a random fashion (hence the name "planet" which in Greek meant "moving" or "wanderer").
Then along came Nicolaus Copernicus. He demonstrated that the observed motions of the planets can be explained without putting Earth at the center of the universe, but instead placing the sun at the centre with all the planets moving around that, making the Earth just another planet rather than being the centre of everything.
His idea's were very controversial at the time, but are considered the birth of modern astronomy.
