b. Johannes Kepler was the first scientist to correctly predict that the planets move in elliptical orbits, not perfectly circular ones. This was a significant breakthrough in astronomy. Kepler formulated three laws of planetary motion, which improved upon the earlier heliocentric model proposed by Nicolaus Copernicus. Kepler's first law, sometimes referred to as the law of ellipses, states that the orbit of a planet is an ellipse with the Sun at one of the two foci.
