How far is Deneb from the Earth?

Answer 1

The distance from Deneb to the earth is still somewhat uncertain. One 2008 study

puts the most likely distance at 1,550 light-years, but there is still a considerable

uncertainty of more than 10%. The reduced parallax uncertainties do not rule out

a distance as close as 1,340 light-years or as far as 1,840 light-years. Deneb is

the farthest first-magnitude star from Earth.

(The number of years required for its light to reach earth is the same as its distance

in light years.)

Answer 2

1,340 light years minimum to 1,540 light years maximum is the estimated distance at the moment.

Answer 3

itis approximately 1,000000,0000000,0000000,00000000
