Johannes Kepler Theory Of The Solar System
Johannes Kepler, German astronomer who discovered three major laws of planetary motion. His discoveries turned Nicolaus Copernicus's Sun-centered system into a dynamic universe, with the Sun actively pushing the planets around in noncircular orbits.

Kepler and his theories were crucial in the understanding of solar system dynamics and as a springboard to newer theories that more accurately approximate planetary orbits. However, his third law only applies to objects in our own solar system.
Kepler's theory changed that and showed how elegantly the planets moved. Kepler's second law says that a line joining a planet and the Sun sweeps out equal areas during equal intervals of time.
He set Kepler the task of understanding the orbit of the planet Mars, which was particularly troublesome. It is believed that part of the motivation for giving the Mars problem to Kepler was that it was difficult, and Brahe hoped it would occupy Kepler while Brahe worked on his theory of the Solar System.
Kepler's laws of planetary motion, in astronomy and classical physics, laws describing the motion of planets in the solar system. They were derived by the German astronomer Johannes Kepler, who announced his first two laws in the year 1609 and a third law nearly a decade later, in 1618.
A biography of Johannes Kepler, from his troubled childhood to his mission to mathematically formalize Copernicus' heliocentric model by finding divine reasoning within the orbits of the planets.
Kepler's Model of the Solar System Johannes Kepler 1571-1630 CE was fortunate enough to inherit an extensive set of naked-eye solar, lunar, and planetary angular position data from the Danish astronomer Tycho Brahe 1546-1601 CE. This data extended over many decades, and was of unprecedented accuracy.
Shape of the Path His discovery made Johannes Kepler the first to understand that the planets in our solar system moved in ellipses, not circles. He continued his investigations, finally developing three principles of planetary motion. These became known as Kepler's Laws and they revolutionized planetary astronomy.
In astronomy, Kepler's laws of planetary motion, published by Johannes Kepler in 1609 except the third law, which was fully published in 1619, describe the orbits of planets around the Sun. These laws replaced circular orbits and epicycles in the heliocentric theory of Nicolaus Copernicus with elliptical orbits and explained how planetary velocities vary. The three laws state that 12
Kepler's law of planetary motion solved the riddle that we live in the Heliocentric Model i.e sun is at the center of solar system, not earth.
