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.
What else can I help you with?
How far can you see the horizon on land?
Depends on how sunny it is that day
How far can a person see or what is a normal visible horizon?
6.23 miles
How far up on a plane do you have to be to see the horizon?
You can see the horizon from any altitude on a plane. The horizon is the line where the sky meets the earth or sea, and it appears at eye level regardless of how high up you are.
You can always see it but it to far away to touch mountains rest on it at sea it surrounds you?
the horizon
How far is the horizon from shore?
The distance to the horizon from the shore depends on the height of the observer's eyes above sea level. On average, a person standing at sea level on the shore can see approximately 3 miles to the horizon. If the observer is standing at a higher elevation, such as on a cliff or in a tall building, they can see farther.
You are in a hot air balloon 400 m above the ground. How far can you see that is how far is your horizon?
It seems like 1,000,000,000,000,000 meters away
Is it be impossible to see any object the distance of the moon or the moon?
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.
How far into the soil do plants grow?
It Maybe B horizon or C horizon
If you can see a plane flying at 36000 feet but it is low over the horizon how far is the plane from the observer?
That depends on the angle of elevation
How far you can see ahead becomes shorter as you reach a hill top?
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.
How far is horizon at 100 ft?
At 100ft, the horizon is approx 12 miles away.
What does on the horizon mean?
The "horizon" is the furthest you can see. "On the horizon" therfore refers to an object which is just in sight.
