How many years does it take Halley's Comet to return to Earth's vicinity?

yes Mark Twain predicted his death on the comets next pass .

I hope I live to see its return...I was too young to really appreciate it's importance the last time around

I remember looking for it in 1986 but couldn't see anything. Also it was freezing outside so I went back indoors quickly.

awww remember vividly laying in the grass with my 4 yr old daughter seeing It Clearly with the naked eye. she still remembers also! WOW Jest LOVE the Starry sky and Astronomy etc 😍
