Johannes Kepler discovered that planets move in elliptical orbits rather than perfect circles. This was based on his observations of the planets' positions over time, which he detailed in his work "Astronomia Nova" in 1609.
Johannes Kepler determined that planets move in elliptical orbits around the sun in the early 17th century. His observations and mathematical calculations led to the formulation of his three laws of planetary motion.
That was Tycho Brahe who lived on an island near Copenhagen and employed the great Johannes Kepler as his mathematician.
Kepler discovered that the planets move in elliptical orbits and he published three laws of planetary motion that explained the details of the ellipses. Kepler's work used observations done by Tycho Brahe, and subsequent observations confirmed that Kepler's laws were correct (they still are). No-one knew why until the later discoveries of the laws of motion and the laws of gravity about 70 years later.

Kepler's observations supported the fact that the plants orbit in an ellipse. He wrote the Laws of Planetary Motion stating all planets orbit the sun and all planets orbits are elliptical.
Johannes Kepler discovered that planets have elliptical orbits in the early 17th century. Kepler's work was based on observations made by Tycho Brahe and his own mathematical calculations. His laws of planetary motion laid the foundation for modern understanding of celestial mechanics.
Kepler showed that the orbits of the planets are elliptical, with the Sun at one of the focal points. This discovery led to his laws of planetary motion, which describe how planets move in their orbits.
Kepler realised the planets orbits are not circles; they are ellipses.

Johannes Kepler discovered that planets move in elliptical orbits by analyzing detailed astronomical data compiled by Tycho Brahe. Kepler's observations and calculations led to his discovery of the Three Laws of Planetary Motion, which revolutionized our understanding of celestial mechanics.

Tycho Brahe, the eccentric Danish recluse, kept records of his observations that later enabled Kepler to establish the elliptical orbits of the planets.
That was Tycho Brahe who lived on an island near Copenhagen and employed the great Johannes Kepler as his mathematician.
Kepler used Tycho Brahe's precise observations to formulate his three laws of planetary motion. Kepler's laws demonstrated that the orbits of planets are elliptical, not circular, with the Sun at one of the foci of the ellipse.
