Johannes Kepler
Kepler discovered that the planets orbit the sun in oval shaped paths called ellipses.
Planets orbit the sun in the shape of an ellipse, which is an elongated circle similar to an oval. When it was first discovered that the Sun is the center of the solar system, it was thought that all the planets had a circular orbit, but the calculations didn't fit.
Kepler described the orbits of planets around the Sun as an ellipse with the Sun at one of the two foci.
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.
The planetary orbits of our solar system are considered "elliptical." This includes "circular" orbits, as a circle is a type of ellipse. In astrodynamics, an elliptical orbit and a circular orbit both fit into the description of a Kepler Orbit.

Johannes Kepler, a German astronomer, discovered that planets follow elliptical orbits around the Sun, rather than perfect circles. This discovery is known as Kepler's first law of planetary motion and was a significant advancement in our understanding of the solar system.
Kepler discovered that the planets orbit the Sun in elliptical shapes. This means that their orbits are not perfect circles, but instead are stretched out ovals with the Sun located at one of the foci of the ellipse.

Newton discovered this with his Universal Theory of Gravity.

No, Brahe did not believe in the heliocentric model; he proposed a geocentric model where planets orbited the Sun and the Sun orbited the Earth. It was Johannes Kepler who later discovered that planets orbit the Sun in an elliptical path, using Brahe's detailed observational data.
Nicolaus Copernicus discovered why planets stay in orbit when he found that the planets revolve around the sun. He is credited with starting the Scientific Revolution through this discovery.
