Invisible to our eyes, ionic "winds" are constantly blowing away from the sun. As a comet passes in a long, elliptical orbit, its tail is pushed away from the sun by these solar winds. Since most of the visible part of the comet is its tail, this is a very visible effect. Of course, there is no air resistance in the vacuum of outer space, a comet's orbit will not make it more elongated, smooth, etc.
yes yes Yes, comets and asteroids usually follow elliptical orbit.
No, comets do.
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.
Comets go around the Sun in a highly elliptical orbit.
A comets orbit is considered a cycle because a comet circles back in an elliptical orbit.

Comets' orbits are elliptical, like all orbiting bodies.
Comets in the solar system follow elliptical orbits around the Sun.
in an elliptical (oval) orbit around the sun, with its tail pointing in the oposite direction of the sun.
Comets typically have elliptical orbits, meaning they follow a path that is elongated and can bring them close to the sun at one point in their orbit and then far away at another point. This results in significant changes in their speed and distance from the sun during their journey.
Yes, the distance from the sun is variable for anything with an elliptical orbit.
