Keplar.
Johannes Kepler discovered the 3 laws of planetary motion.
No. Kepler discovered the laws using Tycho Brahe's data.
3 laws' of planetary motion
Keplar figured out the laws of planetary motion using Tycho Brahe's data.
The laws are known as Kepler's Laws after German mathematician and astronomer Johannas Kepler (1571-1630).
They all obey Kepler's 3 laws of planetary motion.
Johannes Kepler
According to Kepler's laws of planetary motion, planetary orbits are in the shape of an ellipse with the Sun at one of the foci.
"Eponymous" means "Same name". The laws of planetary motion were devised by Johannes Kepler, and are generally called "Kepler's Laws".
Johannes Kepler is credited with forming the mathematics of elliptical orbits.
It was Johannes Kepler 1571-1630 who produced the Laws of Planetary Motion in 1618.
