Planets move in elliptical orbits with the Sun at one of the two foci. This overthrew the 2,000-year-old belief that celestial bodies must move in perfect circles.

I have tried in this work to investigate the motions of the planet Mars, which has always been the most difficult and troublesome of all the planets. For twenty-five years I have labored upon this, and I present here the results of my labors. I have written this book in such a way that it may be read by those who are not versed in the higher mathematics, but who are nevertheless interested in the truth of things.
Before the digital scan, before the printing press even became common, Johannes Kepler was an occultist, a mathematician, and a devoutly religious man trying to hear "God's harmony" in the motion of the planets. In 1600, he traveled to Prague to work with the meticulous Danish astronomer Tycho Brahe.
Published in 1609, the full title translates to "New Astronomy Based upon Causes, or Celestial Physics Treated by Means of Commentaries on the Motions of the Star Mars" . The book documents Kepler's ten-year struggle to understand the orbit of Mars, a project he famously referred to as his "warfare with Mars".
: A line connecting a planet to the Sun sweeps out equal areas in equal times , meaning planets move faster when they are closer to the Sun. Scientific Impact A misleading book title that creates the wrong impression
