http://earthsky.org/brightest-stars/deneb-among-the-farthest-stars-to-be-seen"Deneb is one of the most distant stars you will see with your eye alone.
That’s because it’s one of the most luminous stars in the Milky Way galaxy.
The exact distance to Deneb is unclear,
with estimates ranging from about 1,425 light-years
to perhaps as much as 7,000 light-years.
Whatever its exact distance,
when you gaze at Deneb,
know that you are
gazing across
thousands of
light-years
of space."
