It's simple, really. If you want to know the distance to the horizon you simply have to know your height of eye. That is the distance that ... Using the same formula you would find that 1.17 times the square root of 81 (1.17 * 9) = 10.53 nautical miles (the light house can be seen 10.53 nautical miles over the horizon)

wikiHow article about How to Calculate the Distance to the Horizon. ... Calculate the actual distance you'd have to traverse to get to the horizon by using this formula:; d = R * arccos(R/(R + h)); d = distance to horizon; R = radius of the Earth h = height of eye;

For example, let's say you are on the water in a friend's sport fishing boat and your height of eye is 9 feet above the surface of the water. The formula to calculate distance to the horizon is:

So the distance to the horizon depends on the height of your eyes above the water. If your eyes are 8 inches (20 cm) above the water, the distance of the horizon is about 1 mile (1.6 km) away. A rough formula for calculating the distance to the horizon is:

The distance of the visible horizon as found in the table is greater (4.2 nm) due to atmospheric refraction. The semi-empirical function used is: d = sqrt[ (2x3440.1xh) / (1852xρo) ], where ρo accounts for refraction (0.8279).

Estimating distance to horizon ... (Of course, having looked at the diagram, we should realize that the distance we actually want is represented by an arc but the line segment corresponding to d should be close enough for our purposes, especially as the relative scales of R and h have been grossly exaggerated!)

Re: Horizon distance Date: Thu Apr 16 14:42:40 1998; Posted By: Pauline Barmby, grad student, Harvard University Astronomy Dept.; ... The exact amount of bending depends on a lot of things, such as your altitude, the composition of the atmosphere (which varies with location, weather, etc.). There's no simple formula,
