Greatest when it's closest to the sun, just like
every other body that orbits 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.
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.
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.
Halley's Comet orbits the sun, not the earth, roughly every 76 years.

in an elliptical (oval) orbit around the sun, with its tail pointing in the oposite direction of the sun.
Almost 200 years for one orbit around the sun.
