Johannes Kepler. Inspired Sir Isaac newton's discoveries.
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.
It was Kepler who discovered that the planets orbits are elliptical.
Are all orbits the same shape????
Most orbits are ellipses.
Johannes Kepler showed that IF the planetary orbits are elliptical,THEN that would explain the measurements that Tycho Brahe collectedduring his whole life.Isaac Newton showed that IF gravity works the way he thought it does,THEN the planetary orbits would have to be elliptical.Both of these are only theories. They have never been proven.
An elliptical shape.
Johannes Kepler.
Kepler discovered the orbits of the solar system are elliptical.
