Johannes Kepler
Johannes Kepler proposed that these planets orbit the sun in ellipses, not circles. That is why we have Kepler's Law of Planetary Motion.
Johannes Kepler determined that all planets have elliptical orbits.

Johannes Kepler
Johannes Kepler did that first.
Johannes Kepler determined that all planets have elliptical orbits.
No, that was done by Johannes Kepler.
That they followed elliptical orbits.
No, Johannes Kepler is best known for describing the laws that dictate how orbits work. The Kepler planets were discovered by the Kepler telescope, a spacecraft named in his honor.
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 is credited with that discovery.
