Unformatted text preview: A Z Sun planet After trying complex egg-shaped curves, Kepler concluded that the orbit of Mars is a relatively simple ellipse. He then formulated his elliptical orbits law: all of the planets orbit the Sun in ellipses , with the Sun at one focus. With his third law (D 3 /T 2 = K), published in Harmonices Mundi (1619), Kepler linked the orbital distances and periods of all planets. 1621 Kepler brings out Epitome of Copernican Astronomy : most accessible account of his improved version of heliocentric theory. 1627 Kepler finally published his Rudolphine Tables , based on his system of Sun-centered elliptical orbits. Here for the first time a heliocentric model yielded predictions for the motions of the planets that were far more accurate than those derived from existing geocentric models....
