Elli[tical orbits.
Ellipses
Kepler used Tycho Brahe's data by developing his Laws of planetary motion and by analyzing his observations about planet's orbit.! :D
Johannes Kepler realized that the orbit of Mars is an ellipse with the Sun at one of the foci. This was one of his three laws of planetary motion, known as Kepler's First Law.
Kepler discovered that the planets orbit the Sun in elliptical shapes, not in perfect circles as previously believed. This finding is summarized in Kepler's first law of planetary motion.
Johannes Kepler discovered that planets orbit the Sun in ellipses with varying eccentricities in the early 17th century. This became known as Kepler's first law of planetary motion and revolutionized our understanding of planetary orbits.
Kepler's first law says Neptune has an elliptical orbit with the Sun at one focus. The same goes for the other planets.

Kepler discovered the orbits of the solar system are elliptical.
Kelper determined that the orbit of Mars orbit is not a circle but an ellipse.
