According to Maryln Van DeSavant I seem to recall she said 7 miles. From basic geometry, you get that the distance to the horizon is D=sqrt(2Rh) where D = distance to horizon R = radius of earth h = height of observer, which would be the height of your eyes. R and h have to be in consistent units, of course. In feet the radius of the earth is about 4000 mi * 5000 ft/mi or 20 million feet. Standing on the shore, your eyes are maybe 5 feet above the surface, so D=sqrt(2*20e6*5)= 14000 feet, or a little under three miles. There are some other effects that make that number a little different. Refraction bends your line of sight, so you can see a little bit farther. If you're looking at an object on the water, like a ship, you also get the distance on the other side of the horizion that corresponds to the height of the target. ==How to calculate the distance yourself== To get an "approximate" distance to the oceanic horizon from a particular observation point, take the square root of the height of the observation point, add 22.5%, and that will give you the distance in statute miles. For example, if your eyes were 6 feet off the ground, and you stood atop a 50' tower, your observation point would be 56'. The square root of 56' is 7.48. Add 22.5% of 7.48 (1.68) to 7.48 and you have 9.16 statute miles from your eyes to the horizon.

Depends on how sunny it is that day

Yes. The hilltop is your horizon line. As you approach the top of the hill, the distance between you and your horizon becomes inches, and you cannot see down the other side until you reach the top.

6.23 miles

If you were on the water with an unobstructed view, you would be able to see 2.692 miles or 2.338 nautical miles.

the horizon

Visible distance (in nm) = 1.17 x the square root of the height (in feet) This means, sitting in my sea kayak, the "horizon" is really only about 2 miles away. However, a 50 foot tree on the shore line could be seen 8.5 miles away. !

To the horizon.

It seems like 1,000,000,000,000,000 meters away

Because that's all you can see of the horizon. Tall people see a further horizon, shorter people see a closer one.

if you were at sea level,how far is your vision before the contour of the earthstarts to bend

The "horizon" is the furthest you can see. "On the horizon" therfore refers to an object which is just in sight.

I asume that you mean, standing on land looking out over the ocean. The distance to the horizon would depend on the height of your eye above sea level. If the height of your eye is 6 feet the horizon is about 3.3 statute miles .

That depends on the angle of elevation

Our eyes can only see as far as the horizon, due to the curvature of the Earth. For instance, an observer standing on a hill 100 feet (30 m) in height, their horizon is at a distance of 12.2 miles (19.6 km). Obviously, without the restriction of a horizon, we can look out far into space on a dark night and see our moon and many stars and planets with the naked eye - even better with a telescope.

In the northern hemisphere it is above the horizon or we wouldn't see it.

Actually, the Moon appears larger when it is at the horizon. This is every time you happen to see it near the horizon, but it is only an illusion.Actually, the Moon appears larger when it is at the horizon.

Your at the equator if you see Polaris at the horizon

Your at the equator if you see Polaris at the horizon

In the tropics, not far north of the equator. If you were AT the equator, you wouldn't be able to see Polaris.

at sunset you can see the sun sink below the horizon

Approximately 41 miles- see related link.

Depends on the geography of the area. In a very flat place on land you can see about five miles to the horizon. Somewhere very cold like in Antarctica on the ice sheets the cold can actually bend light allowing you to see Hundreds of miles. On water you can see about 25 miles.

Yes but only the horizon. can't really make anything out but land far away. An amazing sight.

ship

The furthest point an individual can see when looking out to sea is called the horizon. For a 1.8m tall individual, that works out to be approximately 4.8km.
