Kepler's first law of planetary motion published in 1618 says that the planets travel in elliptical orbits with the Sun at one focus. Newton's law of gravity and other work he did explains how the Sun's gravity produces ellpitical orbits.
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.
Planets travel in elliptical orbits.
As an elliptical orbit is any orbit that isn't perfectly circular, everything has an elliptical orbit. The planets Mercury and Pluto have the most elliptical orbits of the planets, and are easily seen to be oval shaped. Comets also have highly elliptical orbits.
All planets have elliptical orbits.
Johannes Kepler.
Planets move around the sun in elliptical orbits. These orbits are elongated and follow Kepler's laws of planetary motion, which describe the shape and dynamics of the planetary orbits.
No, because all planets known have elliptical orbits.
No, not all planets have elliptical orbits. While most planets in our solar system have nearly circular orbits, some planets, like Mercury and Pluto, have more elliptical orbits. Additionally, exoplanets outside our solar system can have a variety of orbital shapes.
ither elliptical, heliocentric, or position!!!

All the planets move with an elliptical orbit, but with a very low eccentricity.
