   What was Kepler's contribution to astronomy?

   • (No less clever [than] Kepler's is the most keen astronomer Wendelin's investigation of the proportion of the periods and distances of Jupiter's satellites, which he had communicated to me with great generosity [in] a very long and very learned letter.

   What data did Kepler use to derive his law?

   • where is the mass of the Sun, is the mass of the planet, is the gravitational constant, is the orbital period and is the elliptical semi-major axis, and is the astronomical unit, the average distance from earth to the sun. The following table shows the data used by Kepler to empirically derive his law: Upon finding this pattern Kepler wrote:

   How did Kepler explain elliptical orbits?

   • From this, Kepler inferred that other bodies in the Solar System, including those farther away from the Sun, also have elliptical orbits. The second law helps to establish that when a planet is closer to the Sun, it travels faster. The third law expresses that the farther a planet is from the Sun, the slower its orbital speed, and vice versa.

   Did Kepler's laws apply to the Solar System?

   • Isaac Newton showed in 1687 that relationships like Kepler's would apply in the Solar System as a consequence of his own laws of motion and law of universal gravitation . A more precise historical approach is found in Astronomia nova and Epitome Astronomiae Copernicanae . Johannes Kepler 's laws improved the model of Copernicus.

   2 days ago · In astronomy, Kepler's laws of planetary motion, published by Johannes Kepler between 1609 and 1619, describe the orbits of planets around the Sun. The laws modified the heliocentric theory of Nicolaus Copernicus, replacing its circular orbits and epicycles with elliptical trajectories, and explaining how planetary velocities vary.

   3 days ago · Figure 4.13 shows the light curves for the first five exoplanet discoveries by the Kepler mission. The drop in intensity also is an indication of the planet’s inclination and its distance from the primary star. The Kepler space telescope of NASA worked between 2009 and 2018 to find a large number of exoplanets in this method.
