It would approach the sun again, but not for a long period of time, until it has gone through the rest of its elliptical orbit.

Comets are balls of ice and dust in orbit around the Sun. The orbits of comets are different from those of planets - they are elliptical. A comet's orbit takes it very close to the Sun and then far away again.
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.
A comet that's bound to the sun and appears periodically is in an elliptical orbit. A comet that whizzes through the solar system only once and then leaves for good is in a hyperbolic orbit. If the comet is periodic but with an exceptionally long period ... thousands of years e.g. ... then we can't tell, from the small part of its orbit that we can see, whether it's elliptical or hyperbolic.
elliptical
A comets orbit is considered a cycle because a comet circles back in an elliptical orbit.
A comets orbit is considered a cycle because a comet circles back in an elliptical orbit.
Any comet visible from earth is in orbit around the sun. If the orbit is closed (elliptical), the comet will return after some period of time. If the orbit is open (parabolic or hyperbolic), the comet will escape the solar system and never return to the neighborhood.
Orbits move in very elongated elliptical orbits.
a comet
Having an elliptical orbit means there is a point for each comet where it is a comet's orbit can be changed over many years by gravity, until it is long and thin.
A comets orbit is considered a cycle because a comet circles back in an elliptical orbit.
Comet
Halley's Comet orbits the Sun, in an elliptical path. It doesn't orbit anything else.
Comets' orbits are elliptical, like all orbiting bodies.
Comets in the solar system follow elliptical orbits around the Sun.
