How far is the horizon? ie. if you were standing on a beach looking out to sea on a clear day...?

Question

what is the distance to the horizon.

Answer 1

Probably about 3 miles.  See http://boatsafe.com/tools/horizon.htm

and

http://en.wikipedia.org/wiki/Horizon

Answer 2

If you are 6 feet then about 14 miles away.

Answer 3

Its 22 Miles because after that the horizon follows the curvature of the earth

Answer 4

13 miles.

Answer 5

It's 3 miles approximately.

Answer 6

has far as you can see

Answer 7

about 12 miles

Answer 8

a long long way

Answer 9

y+z-c+5.6%=distance

Answer 10

Depends where you are standing, how tall you are, high tide or low tide? At sea level, say 6' tall, it would be about 15-20 miles (this is approximate)

Answer 11

about 10km (6 miles)

Answer 12

From the coast of north Essex (facing south east) you can just see on the horizon the rotating generators of the wind farm at Herne Bay in Kent.  These are 40 miles away so that must be the distance of the horizon.  Or does the height of the rotor arms affect this?

Answer 13

you can never reach the horizon

Answer 14

depends how tall you are, and how good your vision is.

Answer 15

22 miles

Answer 16

Of course it depends of your height, but whatever it's definitely about 5 km (3 miles). I found an example:

"For an observer standing on the ground with h = 1.70 m (average eye-level height), the horizon appears at a distance of 4.7 km"

Answer 17

Depends on how tall you are.

Answer 18

Bob beat me too it. It varies tremendously (and rapidly) with the change in height about sea level.

5ft to 6ft is a difference of something like 4 miles (if memory serves me correct).
