because the comet is so far away theat you cant see it without a telescope

Halley's Comet orbits the sun, not the earth, roughly every 76 years.
The time it takes for a comet like Halley's to travel from its farthest point (aphelion) to its closest point to the Sun (perihelion) and back again can vary, but generally it takes about 76 years to make one orbit.
Beacuse that's how long it takes to Orbit the sun And pass the Earth in the process
It takes roughly 75 years for Halley's comet to come by the earth. All comets orbit the sun, but they do not all originate from the same place, which accounts for their paths and how long their individual orbit takes.
It takes Halley's Comet 74 to 76 earth years to complete an orbit of the Sun. It can be influenced by passing the large outer planets, so its revolutions are not always the same duration.
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.

Halley's Comet does not rotate, but perhaps you mean revolve, as in how long it takes to revolve around the sun.If that is what you mean, then the revolutionary period of Halley's Comet is about 75-76 earth years.
The comet responsible for the Leonids meteor shower is Comet Tempel-Tuttle, which takes about 33 years to complete one orbit around the sun. When Earth passes through the debris trail left behind by this comet, we experience the annual Leonids meteor shower.
No it won't. It will be seen from Earth, but it will be a long way from Earth, so it poses no danger to us. You can see many things in the sky at night that are a very long way away. Right now Halley's Comet is too far away to see, but when it is close enough to see, it will still be a very long way from Earth in 2061, just like it was when it was seen in 1986 and in 1910 and other previous occasions that it has been seen from Earth.
Close to 100%, if you wait long enough.
