1. Each planet moves in an elliptical orbit with the Sun at on focus, the other focus remaining unoccupied.
2. The radius vector (the imaginary line between planet and Sun) sweeps out equal areas in equal time (later recognised as the Conservation of Angular Momentum).
3. The square of the orbital period (e.g. in years) is proportional to the cube of the semimajor axis (the average of the minimum and maximum distance from the Sun - e.g. in astronomical units).
What else can I help you with?
How many laws of planetary motion did Johannes Kepler discover?
3 laws' of planetary motion
Which German astronomer and mathematician developed three laws of planetary motion?
Johannes KeplerHis first two laws were published in Astronomia Nova(The New Astronomy) in 1609. His Third Law was published in 1618, in book five of his Harmonices Mundi (The Harmonies of the World.)
What is the evidence for Kepler's universe theory?
Kepler discovered the 3 laws of planetary motion from Tycho Brahe's observations and measurements of the planets' positions. The evidence for the correctness of the theory lies in making predictions of the planets' future positions and then doing further measurements when the time comes, to see if the positions match the predictions. For Kepler's laws these tests were done and it was found that the laws were in fact correct.
What was Johannes Kepler's nickname?
1. planets travel in elliptical orbits around an off-centre sun. 2. the speed of a planet's orbit depends on its distance from the sun. when a planet's close to the sun it, orbits faster. when it's further away from the sun, it travels slower 3. the farther a planet or dwarf planet is from the sun, the longer its orbit *note: did this because there weren't any fricken answers on the web that was specific, easy and in point form answer. Have fun!!!!! (you probably won't) lol :P
Which scientist discovered that planets move in ellipse?
It was months and years of difficult geometrical calculations from measurements made by Tycho Brahe, by his employee Johannes Kepler. When Tycho was alive he would not let Kepler see the results of his work, but he let slip a few figures, tantalisingly, now and again. But after Tycho's death Kepler was clever and devious enough to get his hands on the results, which was fortunate because he had the ability to make use of them. Kepler chose the orbit of Mars as a special subject, which was lucky because it has a relatively high eccentricity that shows up the difference between an ellipse and a circular orbit. After some false starts he realised that the figures fitted an elliptical orbit. Subsequently further observations demonstrated that elliptical orbits gave correct predictions of the positions of Mars and the other planets. Kepler used the heliocentric principle, with the Sun at the centre. Although Kepler and Galileo were contemporary, Galileo never believed that the planets' orbits could be elliptical, and he stuck to the old systems of circles and epicycles of Ptolemy and Copernicus.
Who was the brilliant student of Tycho Brache that formulated the three laws of planetary motion?
No. Kepler discovered the laws using Tycho Brahe's data.
What astronomer first discovered the 3 laws?
Johannes Kepler discovered the 3 laws of planetary motion.

How did Copernicus disprove geocentricism?
Copernicus didn't disprove goecentrism, that was done by Johannes Kepler, who wrote his 3 Laws of Planetary Motion. These were then expanded on by Newton to justify his theory of Gravitation.
What law announced by Kepler was supported by newtons laws?
All 3 of them (Kepler's laws of planetary motion).
What law announced by Kepler was supported by newtons law?
All 3 of them (Kepler's laws of planetary motion).
How many books did Johannes Kepler publish?
Johannes Kepler and his first wife, Barbara Mueller, had 5 children. The first two died in infancy. Johannes and his second wife Susanna Ruettinger, had 6 children. The first 3 Margareta Regina, Katharina, and Sebald died while they were still children. The last three Cordula, Fridmar and Hildebert survived into adulthood. In total, Johannes Kepler had 11 children and only 5 reached adulthood
What is the similarities do the movements of the planets share?
They all obey Kepler's 3 laws of planetary motion.
Are Johannes Kepler's laws still in effect today?
Kepler discovered many things (most of which i cant name right now), however, he came up with 3 new laws of nature. 1. Planets move in elliptical motions, with the sun at one focus point. 2. A line joining the planet and the sun sweeps out equal area over equal time. 3. The time it takes for a planet to orbit the sun squared, is equal to the average distance between the planet and the sun cubed.
