The orbits of periodic comets and the orbits of planets have the same geometric shape.
Every closed gravitational orbit is an ellipse. But the eccentricity of the cometary ellipses
are almost all greater than the eccentricities of the planetary ones.

A comet's orbit can vary in shape from elliptical to highly elongated, sometimes resembling a long, narrow ellipse. This is because comets often have highly eccentric orbits that bring them close to the sun and then far out into the solar system.
Halley's Comet travels in a very long, narrow ellipse.
a comet orbits in a donut shaped path. some comets even go out of our solar system and back into it, past our sun.

A comets orbit is considered a cycle because a comet circles back in an elliptical orbit.

I'm PRETTY SURE that a comet is a sphere-like shape with lots of craters in it, sort of like the moon. A comet has like a small round head with two tails coming out from it. The longest tail is called the ion tail. and the small tail is called the dust tail.
It is called an orbit. A comet has an eccentric or parabolic orbit.
No, Halley's comet orbits the sun and its orbit is not the same each time it passes by Earth. The orbit of Halley's comet is an elliptical shape, so its distance from Earth and speed can vary during each approach.
Comets' orbits are elliptical, like all orbiting bodies.
