75 - 76 year to orbit the sun .
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.
Halley's comet.
Halley's Comet orbits the sun, not the earth, roughly every 76 years.
Halley's comet
Halley's Comet takes 73.5 years to orbit the sun but every comet is different just like planets.
Halley's comet is unique is that it takes 76 years to be visible from the earth on like other comets that can be seen annually
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.
For the Earth, it takes 365 days to revolve around the Sun.
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.
Yes, it takes 74 years to omplete its orbit I think it was last seen was in 1985 or 1986
It takes 4 years for th earth to revolve around the sun.
Beacuse that's how long it takes to Orbit the sun And pass the Earth in the process
