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.
He discovered that they were not perfect circles. Also, he was pretty good a math, and devised what are known as "Kepler's Laws of Planetary Motion," by which you can predict the movement of the planets based on their orbital distances and speeds.He worked out that the planets revolve round the Sun in elliptical orbits, with the Sun at one of the two foci.
Johannes Kepler was the first person to prove that all of the planets are in elliptical orbits, but he was unable to propose any mechanism that would cause this. Based largely on Kepler's work, Isaac Newton was able to invent the calculus of infinitesimals and to propose his law of universal gravitation, providing a mechanism that would cause the planets to behave in accordance with Kepler's laws. Newton's later comment "If I have seen further than other men, it is because I have stood on the shoulders of giants" was in direct reference to Kepler's essential contributions.
17th century astronomer Johannes Kepler discovered the elliptical shape of the planets' orbits around the Sun, which he described in his first law of planetary motion. Newton later explained this in his law of universal gravitation.

Johannes Kepler showed that IF the planetary orbits are elliptical,THEN that would explain the measurements that Tycho Brahe collectedduring his whole life.Isaac Newton showed that IF gravity works the way he thought it does,THEN the planetary orbits would have to be elliptical.Both of these are only theories. They have never been proven.
All orbits are ellipses, a sort of oval. Kepler's laws didn't give people enough information to actually calculate an orbit, but his work was fundamental to Isaac newton's work in developing theories of gravity and developing calculus.
The true shape of planetary orbits was discovered by Johannes Kepler in the early 17th century. He formulated three empirical laws, now known as Kepler's Laws of Planetary Motion, which describe the motion of planets in the Solar System. These laws are as follows: The orbit of each planet is an ellipse with the Sun at one of the two foci. A line joining a planet and the Sun sweeps out equal areas during equal intervals of time. The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.Kepler's Laws of Planetary Motion provide a mathematical description of the motion of planets in the Solar System and explain why planets move in elliptical orbits around the Sun.
