Like any other freely moving body in the universe they exert gravity on other bodies around them and they are attracted by other heavenly bodies as well. Each body exerts a force of gravity upon other nearby bodies in space.
Comets tend to have a more elliptical path around the sun, though, than do most other major satellites of the sun.
Comets are celestial objects that have tails and move around the sun. When a comet is moving toward the sun, its tail points toward the sun.
Particles around a comet usually include dust and gas that are released as the comet approaches the sun. These particles form a glowing cloud called a coma which envelops the nucleus of the comet. As the comet gets closer to the sun, the solar wind pushes on the particles in the coma, creating the tail that points away from the sun.
It is called an orbit. A comet has an eccentric or parabolic 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.
A comet is visible for only a short portion of its orbit around the sun because it only becomes bright and visible when it gets closer to the sun. As it approaches the sun, the sun's heat vaporizes the comet's icy surface, creating a glowing coma and tail that make it visible from Earth. Once the comet moves away from the sun, it becomes dimmer and harder to see.
Considering that comets are pretty common objects in the solar system and that we have one sun only, it's obvious that a comet needs just one sun, or star, to go around.

Halley's Comet is still orbiting the Sun. It was close to Earth in 1986.

Comet Hale-Bopp orbits the Sun. It is a very long-period comet; we expect it back in about 2200 years. Perhaps before then we'll go out and get it.
