What do comets orbit
A
The Stars
B
The Planets
C
The Sun
D
None of the above
Explanation: 

Detailed explanation-1: -Orbit of a Comet. Comets go around the Sun in a highly elliptical orbit. They can spend hundreds and thousands of years out in the depths of the solar system before they return to Sun at their perihelion. Like all orbiting bodies, comets follow Kepler’s Laws-the closer they are to the Sun, the faster they move.

Detailed explanation-2: -If the planet is large enough it can happen easily. Shoemaker Levy-9 was a comet that was captured by Jupiter and orbited it at least once, perhaps more than once, but given the highly eccentric orbit, perhaps only once.

Detailed explanation-3: -Most comets travel in highly elliptical orbits around the Sun with orbital periods (time between returns) ranging from just over three years to millions of years. Some comets, called “periodic comets", return near the Sun every few years, and travel no further from the Sun than the orbit of Jupiter.
