Through years of research, and a lot of trial and error, Kepler was able to show that three laws accurately describe planetary motion. He was never able to explain WHY these laws worked, he only knew they DID.
Kelper determined that the orbit of Mars orbit is not a circle but an ellipse.
Kepler discovered the orbits of the solar system are elliptical.
That they followed elliptical orbits.
Yes, except that they are not my planets.
true
Johannes Kepler proposed that these planets orbit the sun in ellipses, not circles. That is why we have Kepler's Law of Planetary Motion.

He is best known for his laws of planetary motion.

There is no planet named Kepler. There are, however, many planets with designations such as Kepler-22b. These planets are named as such because they were discovered using the Kepler spacecraft. The spacecraft is named after Johannes Kepler, a 16th-17th century astronomer who defined the laws of planetary motion.

3 laws' of planetary motion
Johannes Kepler did not discover any planets but he did something much better, he discovered the laws of planetary motion, which apply to all the planets and everything else in the solar system, definitely more than 100,000 objects.
Johannes Kepler developed the laws of planetary motion.However he was German not Austrian.
Laws of Planetary Motion by Johannes Kepler, published 1618.
He is best known for his laws of planetary motion.
I'm pretty sure you're thinking of Johannes Kepler.
Kepler discovered that the planets move in elliptical orbits and he published three laws of planetary motion that explained the details of the ellipses. Kepler's work used observations done by Tycho Brahe, and subsequent observations confirmed that Kepler's laws were correct (they still are). No-one knew why until the later discoveries of the laws of motion and the laws of gravity about 70 years later.
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.
