The Sun
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.
An orbit
It is called an orbit. A comet has an eccentric or parabolic orbit.
An orbit
The comet is kept in orbit around the sun by the gravitational pull between the comet and the sun. This gravitational force acts as a centripetal force, keeping the comet moving in its elliptical orbit.
in an elliptical (oval) orbit around the sun, with its tail pointing in the oposite direction of the sun.
The path of a comet around the sun would depend on its mass, speed, and trajectory. It a comet enters the sun's gravitational field at the correct trajectory and speed, it would fall into a roughly circular 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.
Almost 200 years for one orbit around the sun.
The orbit of the earth, around the sun is elliptical. And, I expect that you are living on the earth and orbiting the sun every day.
