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.
2,537 years
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.
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.
It's still traveling in outer space...where else could it be? And hopefully the 3 Saturn Shaped UFO's that came with it, that I observed while on Earth have finished their mission. TRUE THAT!!
That varies completely from comet to comet.
That depends on what you call 'long' or 'short'. Halley's period is in the neighborhood of 75 years, give or take a few years. Since that's short enough for two perihelions to occur within a single human lifetime, I guess it ought to be considered a short period.
The orbital period of Halley's Comet is about 75.3 years.
That will completely depend on where the Earth and the comet are in their respective orbits. No single answer is possible.
unsa man
it depends
76 years
Halley's Comet returns once every 75-76 years.
