how far away is the horizon ?
its not a gotcha I was just wondering and you seemed quite knowledgeable.
As far as the eye or camera lens can see????
I was asking Hiromant how far away the horizom is physically because it was on his long list of things but he never mentioned the official distance.
That depends on the height of the viewpoint. For a normal person at sea level it's around 5 km if I remember correctly.
that doesnt sound right as I can see a lot further than that along the coast ( tide line to tide line on the beach )
Are you sure that number is correct ?

Perceived distance varies depending on weather conditions. Height of viewer. This is the official formula. Plug in your own numbers.
