Yes, none of the planets in our solar system have exactly circular orbits, though some are more eccentric than others.
All the planets have elliptical orbits but Uranus and Neptune have slightly different orbits than other planets on solar system.
All planets have elliptical orbits.
No, because all planets known have elliptical orbits.
It was Kepler who discovered that the planets orbits are elliptical.
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 planets in our solar system have 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.
Planets travel in elliptical orbits.
Mars, and all the other planets, have oval-shaped, or eliptical, orbits.

The planets orbits are the routes or paths that the planets follow around our sun. One orbit is one trip around the sun (one year).
