What did Kepler discover?
Using the precise data that Tycho had collected, Kepler discovered that the orbit of Mars was an ellipse. In 1609 he published Astronomia Nova, delineating his discoveries, which are now called Kepler's first two laws of planetary motion.
What is Kepler’s greatest discovery?
His most famous accomplishment are his three laws of planetary motion which laid the foundation of celestial mechanics. Kepler discovered that planets move in elliptical orbits and at different speeds at different times, according to their distance from the sun.
What are the 3 laws discovered by Kepler?
There are actually three, Kepler's laws that is, of planetary motion: 1) every planet's orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet's orbital period is proportional to the cube of the semi-major axis of its …
What was Kepler’s idea or discovery?
Johannes Kepler was a German mathematician and astronomer who discovered that the Earth and planets travel about the sun in elliptical orbits. He gave three fundamental laws of planetary motion. He also did important work in optics and geometry.

Why was Kepler’s discoveries important?
He regarded them as celestial harmonies that reflected God's design for the universe. Kepler's discoveries turned Nicolaus Copernicus's Sun-centred system into a dynamic universe, with the Sun actively pushing the planets around in noncircular orbits.
How did Kepler’s discoveries contribute to astronomy?
