Comets do indeed have orbits. Sometimes the orbits take thousands of years. For the most part, they stay in these orbits unless affected by the gravity of another body.
Virtually NOTHING in space is in a circular orbit; every body out there is in an elliptical orbit. Some are CLOSE to circular, but I don't believe than any are quite exact. Comets especially are in VERY elliptical orbits. If their orbits were even nearly circular, their ices and volatile gasses would have been evaporated long ago.
Comet orbits are typically elliptical, meaning they are elongated and not circular like planet orbits. This can result in comets having highly eccentric paths around the Sun.
No, I've yet to find a single comet with a circular orbit. All I've researched have elliptical orbits, and the apogee of that orbit, the point furthest from the Sun, takes them to the Oort Cloud or beyond.
Comets go around the Sun in a highly elliptical orbit.
It has been suggested that comets originate in the Oort cloud and then travel in long elliptical orbits around the Sun.
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 orbits are geodesic curves. Comets tend to have elliptical orbits ... as do planets, really; the degree of eccentricity (this is a measure of how "stretched" the ellipse is) just tends to be higher for comets.

Comets travel in highly elliptical orbits. See link for more.
yes yes Yes, comets and asteroids usually follow elliptical orbit.
The Earth orbits in the plane of the ecliptic in an ellipsoidal orbit that is nearly circular. Comets orbits are highly elliptical and mostly out of the plane of the ecliptic.
Yes some elliptical orbits are more circular than others
Comets. Periodic comets have highly eccentric elliptical orbits, with eccentricities.
elongated elliptical orbits around the sun
they have long elliptical orbits
The Earth's orbit around the Sun is more circular and consistent, while a comet's orbit is typically more elliptical and variable. Comets also come from the outer solar system and have highly eccentric orbits that can bring them close to the Sun, leading to the development of a bright coma and tail due to the heat and radiation.
