Johannes Kepler was a sky researcher who lived almost 450 years ago and spent a large part of his life in Linz. The mathematician and astronomer became famous for his teaching about the celestial bodies by proving mathematically that the sun is at the centre of our universe, not the earth, and that the planets move around the sun, not the other way round.
