All planets have elliptical orbits.
The planet with the most elliptical orbit is Mercury. Second is Mars.
Elliptical
No the planet's orbits are not VERY elliptical but yes, they are somewhat elliptical. They are not just rotating in a circle. More like an oval.
It was a German astronomer by the name of Johannes Kepler who did a whole lot of geometrical calculations from new and unusually accurate observations made by Tycho Brahe. Kepler showed that the planets each move in an elliptical orbit and he gave three laws describing exactly how they move, and it was found to be much more accurate than the previous models of Ptolemy and Copernicus. He did not know why they behaved as they did and we had to wait until Isaac Newton explained it using his new theory of gravity.
You are thinking of Pluto. Pluto is now designated a minor planet.
The shape of a planet's orbit is elliptical.

Mars has the most elliptical orbit. The earth's is almost a perfect circle
The planet with the most elliptical orbit is Mercury. Second is Mars.

Elliptical
the answer is: the elliptical orbit of the planet
The motion of the planets are elliptical motions
All of them do.
Elliptical Orbit.
It varies from planet to planet. But most planets including our own, orbit the star in an elliptical motion.
