Kepler discovered that the planets orbit the sun in oval shaped paths called ellipses.
Johannes Kepler determined that all planets have elliptical orbits.
Ellipse
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.
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.

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.

Johannes Kepler determined that all planets have elliptical orbits.
Johannes Kepler stated that the planets revolve around the sun in an ellipse.
It was Johannes Kepler 1571-1630 who produced the Laws of Planetary Motion in 1618.
