He was a german astronomer and a natural philosopher, noted for formulating and verifying the three laws of planetary motion. These laws are now known as Kepler's Laws.
Kepler held the chair of Astronomy and Mathematics at Graz University from 1594 until 1600, when he became assistant to the Danish astronomer Tyco Brahe in tn the latter's observatory near Prague. On the death of Tycho in1601, Kepler assumed his position as imperial mathematician and court astronomer to Rudolf II, Holy Roman emperor.
Kepler was able to derive from the notes of Tycho, a detailed picture of the path of the planet Mars. Whereas all previous investigators had struggled to fit the planetary paths to circles, Kepler, by using Tycho's superb data was able to show that Mars did not move in a circular path, but rather in an elliptical one.
The shape of an ellipse is described by its long and short dimension called its major and minor axes, respectively. Kepler's discoveries of the nature of planetary motions are expressed in what are known today as Kepler's Three Laws. These laws describe the essential features of planetary motion around the sun. They also describe not only the shape of a planet's path, but also its speed and distance from the sun.

As for Kepler's Laws, they have an additional significance. Kepler's Laws are the first mathematical formulas to describe the heavens above and change the way man thinks about space and beyond.
One of the largest contributors to the field of astronomy was Johannes Kepler. ... Using data collected by Tycho Brahe, to whom Kepler was an assistant, Kepler was able to formulate the three major laws of planetary motion. ... Kepler's Second Law of Planetary Motions has to do with equal areas. ... Kepler's final law has to do with space and time. ... For example, Sir Isaac Newton utilized Kepler's Laws of Planetary Motion in his research. ...
Johannes Kepler (1571-1630) Johannes Kepler was born in Weil der Stadt in Swabia, in southwest Germany, not far from France. Kepler was born on December 27, 1571, a premature child. ... Kepler is most famous for his discovery of the three laws of planetary motion. ... Kepler developed his experimental laws from Brahe's data on Mars. ... Kepler died in Regensburg in the year 1630. ...
Here is a diagram that shows the approximate Habitable zone of the star Kepler-442 and where Kepler-442b is compared to the zone. ... Extrasolar planet kepler-442b [Image]. (2015). ... NASA, using over $600 million created the Kepler space observatory. ... The exoplanet Kepler-442b is found it its star's habitable zone. ... Kepler-442b distance from its sun, Kepler 442, changes many of its characteristics such as the possibility of life. ...
Only until Galileo and Kepler did heliocentric view of the universe become prominent. ... However, Copernicus" model would not gain popularity and understanding until Galileo and Kepler. ... Kepler would be the next step to creating a sound solar system that met with observation. ... Kepler was assigned the task by Tycho Brahe to analyze the observations that Tycho had made of Mars. ... Copernicus, Galileo, and Kepler provided huge contributions to astronomy. ...
A few scientists that challenged Aristotle's ideas were Copernicus, Brahe, Gilbert, Kepler, Galileo, Descartes, and Newton. ... Kepler created three laws of planetary motion known as Kepler's Laws, which are still valid today. ... Newton used Gilbert and Kepler's speculation of natural magnetism of the Earth and Galileo's measurements of the force of gravity at sea level to find gravitation. ...
Johannes Kepler was a mathematician born in a small town in Germany in 1571 A.D. ... Kepler's First Law: Each planet's path around the Sun is and ellipse, with the Sun at one focus of the ellipse. ... So what Kepler means by his first law is that every plant follows a specific Elliptic path around the sun. ... In Somewhat Plain English: Basically what Kepler's second law describes how the orbital speed of a planet changes as a planet revolves around the Sun. ... Kepler's Third Law: The ratio of the cube of the semimajor axis of a planet's orbit to the squa...
Half a century later, Johannes Kepler came into the picture. ... Brahe died and left Kepler to finish his work. Kepler went to college because he felt he had to prove Copernicus theory. ... Kepler would not of developed his laws without Copernicus terms. Isaac Newton would not of developed his theory on gravity if Kepler did not developed his third law. ...
Besides Nicolaus Copernicus, there were also some well-known astronomers such as Johannes Kepler and Galileo Galilei at that time. ... For example, the discovery of logarithm just in time refined Johannes Kepler's theorem. ... As it was mentioned before, Euclid's Element as a mathematics book significantly helped Kepler to refine the theorem of Copernicus. Similarly, John Napier, a Scottish mathematician helped Kepler to refine his theory through mathematical method unintentionally. ... And the discovery of logarithms is also famous for helping Kepler. ...
After Copernicus's death, a young astronomer and mathematician, Jonannes Kepler, began studies to support and improve Copernicus's theories. Kepler's writings impressed a man by the name of Tycho Brache, who was a Danish astronomer. Brache was so impressed that he appointed Kepler as the court mathematician in the Holy Roman Empire in 1601. ...
