What is the interval of the appearance of Halley's comet?

Answer 1

You can't see Halley's Comet at any time of the day or night now. It was last seen from Earth in 1986 and won't be seen from Earth again until 2061. It orbits the Solar System, taking about 75 to 76 years to do so, so it can only be seen about that often from Earth.

Answer 3

Halley's comet has a period of 75 -> 76 Years.

It was last observed in 1986 and is predicted to return to perihelion on July 28th, 2061.

Answer 4

About every 75 to 76 years. Its orbit could be slowed slighltly by the gravitational influence of planets like Jupiter and Saturn.
