planetary motion laws
1687Newton first published these laws in Philosophiae Naturalis Principia Mathematica (1687) and used them to prove many results concerning the motion of physical objects. In the third volume (of the text), he showed how, combined with his law of universal gravitation, the laws of motion would explain Kepler's laws of planetary motion.http://www.nationmaster.com/encyclopedia/Newton%27s-second-law-of-motion
Laws of Planetary Motion by Johannes Kepler, published 1618.

Keplar.
Johannes Kepler discovered the 3 laws of planetary motion.
No. Kepler discovered the laws using Tycho Brahe's data.
Johannes Kepler introduced the concept of elliptical orbits in the early 17th century. His laws of planetary motion replaced the previously held idea of perfect circular orbits. This advance in understanding planetary motion led to the development of modern celestial mechanics.
Isaac newton discovered the three principles of planetary motion
There are no fundamental laws behind the Copernican theory. The three laws of planetary motion that we use now were discovered by Johannes Kepler and published in 1609, sixty-six years after Copernicus died. Kepler introduced the new idea of elliptical orbits. The idea that the Sun is at the centre (loosely speaking) was the only part of the Copernican theory that Kepler retained.
17th century astronomer Johannes Kepler discovered the elliptical shape of the planets' orbits around the Sun, which he described in his first law of planetary motion. Newton later explained this in his law of universal gravitation.
Johannes Kepler discovered that the orbits of planets around the Sun are elliptical in shape. Kepler's work on planetary motion led to his three laws of planetary motion, which revolutionized our understanding of the solar system.
It was Johannes Kepler 1571-1630 who produced the Laws of Planetary Motion in 1618.
