Johannes Kepler
Elliptical orbits of the planets around the sun actually match what we observe. Newton's Theory of Universal Gravitation states that planets will move around the sun in elliptical orbits.

All the planets have elliptical orbits but Uranus and Neptune have slightly different orbits than other planets on solar system.
Elliptical
The elliptical orbit of planets is a result of the gravitation of the sun and the tangential velocity of the planet.
Johannes Kepler was the first to state that planets move in elliptical orbits.
The planets move intheir ellipticalorbits becauseof the gravitation of the Sun combined withthe inertial velocity of the planets(tangentialto their orbital paths). Mathematics shows the resulting orbits must be ellipses. (Some of the ellipses are in factalmost circles.)
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.
Planets move in elliptical orbits. The average of Saturn is 1,433,000,000 km
All the planets move with an elliptical orbit, but with a very low eccentricity.
