i dont know you tell me
He wrote many unwritten laws
Kepler's observations supported the fact that the plants orbit in an ellipse. He wrote the Laws of Planetary Motion stating all planets orbit the sun and all planets orbits are elliptical.
Kepler studied the planets' orbits and published his three laws of planetary motion, in 1609 and 1619. His most famous work was probably the 1609 book called "Astronomia Nova".
He is best known for his laws of planetary motion.
The general laws about the planets' orbits were known before Newton - mainly, through the three Laws of Planetary Motion, by Kepler. Newton showed that the movement - as explained in Kepler's Laws - was a result of the laws of motion (especially Newton's Second Law), and of the force of gravitation.
The ruler that wrote the first code of laws was Hammurabi.
That's one of Kepler's three laws of planetary motion, which he figured out fromstudying Tycho's lifetime of watching the planets and keeping notes.About 100 years after Kepler, Newton wrote his theory of universal gravitation,and showed that if gravity is true, then the planets mustbehave that way.
All of them.
The Babylonian Emperor Hammurabi is known as the person that wrote the first set of laws. These laws are called Hammurabi's Code.
There are numerous theories of planetary motion. Ptolemaeus (earth in the centre), Copernicus (the sun in the centre, planets orbit around it), Kepler (planet orbits are ellipses) all wrote such theories.
Your mommy
Johannes Kepler developed the laws of planetary motion.However he was German not Austrian.
