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.
Horizon means an imaginary line where the Earth meets with the Sky.
This happens when we look at sky and Land together from a distance
Hence we can never reach the horizon
If you mean horizon...standing at sea level, eye level at 6 feet, distance is 3 miles.
from 100 feet high, the distance is 12.3 miles
from 200 feet high, the distance is 17.3 miles
from 300 feet high, the distance is 21.2miles
Lying on fairly flat beach -- eye height 1/2 metre -- horizon 2.5 km
Child standing at water edge -- eye height 1 metre -- horizon 3.6 km
Adult standing near water edge -- eye height 2 metre -- horizon 5.1 km
Low dune at back of beach/lifesavers' tower -- eye height 5 metre -- horizon 8 km
All of these are "geometric horizons". Actual distances to the horizon -- "optical horizons" -- are usually a little greater than this. An extra 15-20% is typical. Sometimes atmospheric conditions produce a much greater horizon distance.
1.17 multiplied by the square root of the height of your eye in feet.
If your eye-line is at a height of 1.70 metres while standing on the seashore, the horizon is 4.65 km away.
The distance of the hoizon is dependant on your height of observation.
If you are 6 feet above the sea level, the hoizon is 3 miles away.
Depends on how sunny it is that day
6.23 miles
the horizon
There is no horizon in deep space.
It seems like 1,000,000,000,000,000 meters away
B Horizon
You can't reach the horizon. No matter where you are or what you do the horizon will always be there in front of you. The distance between the shore and the horizon is infinite.
It Maybe B horizon or C horizon
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.
That depends on the angle of elevation
At 100ft, the horizon is approx 12 miles away.
Because that's all you can see of the horizon. Tall people see a further horizon, shorter people see a closer one.
