There are no fundamental laws behind the Copernican theory. The three laws of planetary motion that we use now were discovered by Johannes Kepler and published in 1609, sixty-six years after Copernicus died.
Kepler introduced the new idea of elliptical orbits. The idea that the Sun is at the centre (loosely speaking) was the only part of the Copernican theory that Kepler retained.
First: all planets travel in an elliptical orbit with the Sun at one focus
Second: if a line is drawn from the Sun to a planet, the area that the line sweeps across is equal at different distanes for equal times
Third: There is a relationship between the distances of a planet from the Sun and it's speed
Kepler's work effectively eliminated the idea of uniform circular motion as well as the idea of crystalline spheres revolving in circular orbits.
Celestial objects in orbit.
Keplers Laws
It is the third law
Kepler's second law the law of equal areas.
It is Kepler's first law which says the planet moves in an ellipse with the Sun occupying one focus and the other focus is vacant.

Keplers Laws
It is the third law
Known for his eponymous laws of planetary motion.
Mindboggling? They are "Laws of Planetary Motion". So I guess the answer is "motion".
Isaac Newton
he supported his ways and thiught of better ways to replace keplers half right ways
Kepler's second law the law of equal areas.
Distance from the body and the mass of the body. See Keplers laws of planetary motion for more info.
Johannes Kepler(1571-1630) was a German astronomy and natrual philosophere who was known for his ability in formulating and verifying the three laws of planetary motion, which are now known as Keplers's Laws.
April 27, 4977 B.C. That was when he once calculated that the universe began. Or, you may mean when he published his Laws of Planetary Motion. He published his first 2 laws in 1609 and his 3rd law around 1619.
It is Kepler's first law which says the planet moves in an ellipse with the Sun occupying one focus and the other focus is vacant.
