Keplers laws.
Kepler deduced that the planets orbit about the sun in an elliptical pattern described by the mass at one focus of two. When the planet (or any satellite for that matter) is closer to the extreme of the ellipse closer to the "real mass" focus, it will travel faster through space, however, when going about the opposite extreme, it will travel slower. The ratio at which this happens is difficult to describe but I will say that the planet will cover the same amount of "area" with the "massive" focus as a center as anywhere else.
The reason that it is an ellipse and not a circle? well, the chances of a stranded loner mass enters the gravitational field of a greater mas at just the right angle and a just the right speed are very small. An ellipse is simply easier to manage, at least for nature.
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 the planets move with an elliptical orbit, but with a very low eccentricity.
In one word 'YES'. The paths that you describe are the planets orbits. These orbits are shaped like 'Ellipsoids'., that is an ellipse that doesn't quite close-up , but overloops with every circuit. The Sun lies not at the centre of the ellipsoid, but at one of the foci. As a consequence planets following their orbits paths speed up (Nearest the Sun) and slow down (Furthest from the Sun).
They are orbits and they are elliptical in shape. So the answer could be "orbits" or it could be "ellipses".
Orbits of planets are oval, or elliptical, because one point in the orbit where Earth is closest to the Sun, and another is farthest from the Sun. Therefore making it oval. Hope that makes sense.
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 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.

Kepler
Elliptical
Yes, planets move around the sun in elliptical orbits due to the gravitational force between the sun and the planet. This motion is governed by Kepler's laws of planetary motion.
The orbits of the planets around the Sun are not spherical as many people imagine but are in fact elliptical.
Planets travel in elliptical orbits.
