It is difficult to pin down a comet's orbit all that precisely; we have a difficult enough time predicting the MONTH, much less the second. There are many small and unseen objects in the outer solar system that can perturb the orbit of a comet and cause it to be either early or late returning to the Sun.
Halley's Comet has a period of about 76 years, and should be visible in 2061. But there is a (very tiny) chance that it will hit something in the darkness of space far beyond Pluto and never be seen again.
Who knows? Perhaps by that time, we'll be able to catch it and put it in the Smithsonian.

What does hale-bopp orbit around?
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.

How long do you go to school to be a tractor mechanics?

What part or parts of a comet come and go during a comet's orbit?
The tail. The tail is composed of gas and dust released from the comet nucleus when it approaches the Sun. Comet tails can be incredibly long, some as long as 150 million kilometers. As the comet recedes out into the Solar System away from the warmth of the Sun, it stops shedding dust and gas and the comet loses its tail.
