Johannes Kepler and Tycho Brahe worked together beginning in 1600. Kepler used Brahe's extensive and accurate observations to create his own model of the universe. Kepler's model was also based on mathematics, and one of his first discoveries was that the orbit of Mars is an ellipse with the sun at one focus, and the speed of the planet in its orbit varying in a calculable way. This information was discovered in 1609 and is the basis of the first and second of Kepler's Three Empirical Laws. The first law states that the orbit of each planet is an ellipse with the Sun at one focus. The second law states that the radius vector to a planet sweeps out equal areas in equal intervals of time. Kepler formulated his third law in 1619; it states that the squares of the sidereal periods of the planets are proportional to the cubes of the semimajor
Galileo Galilei believed that the universe could be explained by a series of mathematical relationships. He argued that nature displayed mathematical regularity in its most minute details.
Philosophy is written in that great book which ever lies before our eyes - I mean the universe - but we cannot understand it if we do not first learn the language and grasp the symbols in which it is written. This book is written in the mathematical language, and the symbols are triangles, circles, and other geometrical figures, without whose help it is impossible to comprehend a single word of it; without which one wanders through a dark labyrinth

In Kepler's time it was thought that a force might be acting to keep the planets around the Sun, but Isaac newton worked out that the elliptical orbits discovered by Kepler would be maintained exacty by a force that obeyed Newton's law of gravity.
To do this he needed Newton's law of motion that says force = mass times acceleration. Also Newton had to invent the theory of differential calculus to show that a planet moving in a circle or an ellipse would be accelerating towards the Sun at exactly the right rate required by the theory. After nearly 2000 years the problem of planetary motion was solved.
Since then the model has been refined by the theories of relativity but even so Newton's model is still extremely accurate.
Kepler discovered the orbits of the solar system are elliptical.
No, Kepler-22b is not part of our solar system. It is an exoplanet located about 600 light years away in the constellation of Cygnus.
Kepler used Tycho Brahe's data to establish the heliocentric theory of the solar system.
kepler determined the planetary orbits were elliptical
No. It is a planet in another solar system about 500 light-years from Earth in the constellation Cygnus.

Not part of our Solar system - but it is believed to be orbiting a star similar to our own.
Kepler-22b is smaller than Jupiter. Jupiter is the largest planet in our solar system, while Kepler-22b is an exoplanet located outside of our solar system and is estimated to be approximately 2.4 times the size of Earth.

Johannes Kepler
The only part of Copernicus's theory that Kepler retained was the idea that the Sun is at the centre of the Solar System.
Kepler and Copernicus found solar system and said that earth revolves around the sun.
Planets do not orbit the solar system: they orbit the sun and remain inside the solar system.Planetary motion can be calculated from Kepler's laws.
