It changes so it will next be seen in 4337
Hyakutake is a long-period comet. Before its most recent passage through the solar system, its orbital period was about 17,000 years, but the gravitational influence of the giant planets has increased this period to 102,070 years.
Halley's Comet was a periodic comet; it returns to the inner system every 76 years. Hale-Bopp is a very long-period comet; it may have been last seen in 2215 BC. That may have been Hale-Bopp's first approach to the Sun; its orbit was likely altered by close brushes with Jupiter then, and again during its last pass in 1997. Hale-Bopp's next appearance may be in or around the year 4530 AD.
Comets such as this are in long drawn out eccentric orbits around the sun. It is likely that this comet was once in a slow distant orbit around the sun, on the edge of our solar system around the orbit distance of Pluto, or further. It may then have been knocked into it's current orbit through a collision with another object.
That depends on where in its orbit the comet is. Near the Sun, the comet was moving VERY fast indeed, but in 1200 years or so, a few hundred AU from the Sun, it will hardly be moving at all. And then it will begin to make its long fall back into the inner solar system.
The comet seen around 1991 is Comet Hale-Bopp, officially designated C/1995 O1. It was discovered independently by Alan Hale and Thomas Bopp in July 1995, but it became prominent in 1996 and 1997, when it was exceptionally bright and visible to the naked eye for several months. Hale-Bopp is one of the brightest comets of the 20th century and is notable for its long tail and its prolonged visibility, attracting significant public interest and scientific study.
Long period comet
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.

Comet Hale-Bopp has an orbital period of approximately 2,533 days, or about 6.9 years. This means it takes nearly 7 years to complete one full revolution around the Sun. The comet was last visible from Earth in 1997 and is not expected to return until around 2024.
Comet Hale-Bopp is still visible in very large telescopes; estimates indicate that it will be visible until 2030, and may be visible longer than that in the improved telescopes of ten years from now.Comet Hale-Bopp is not expected to return to the inner solar system until the year 4390.

Comet Hale-Bopp was visible in 1997 and was significant in the field of astronomy because it was one of the brightest comets seen from Earth in the 20th century. Its long and bright tail made it a spectacular sight for observers around the world.
Comets like Hale-Bopp do not rotate on their axis like planets or moons. Instead, they follow an orbit around the Sun. Hale-Bopp has an orbital period of about 2,533.6 years, which means it takes that amount of time to complete one orbit around the Sun.
That all depends on the comet Halley's takes about 76 years where as Hale Bopp takes about 2300 years. Its the same principle with the planets the closer the orbit the faster it goes. Some Comets like Hale Bopp come from the Oort cloud about a light year away that is why it takes so long, where as Halley's goes out round Pluto and back again.
