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
Kepler discovered the orbits of the solar system are elliptical.
No. Kepler-22b is in another solar system about 620 light years away.
Kepler used Tycho Brahe's data to establish the heliocentric theory of the solar system.

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
Kepler and Copernicus found solar system and said that earth revolves around the sun.
The only part of Copernicus's theory that Kepler retained was the idea that the Sun is at the centre of the Solar System.
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.
