(Of course, the height of the eye, and consequently the distance to the horizon, is greatly exaggerated in this diagram.) The observer's astronomical horizon is the dashed line through O, perpendicular to the Earth's radius OC. ... So let's try to allow for that curvature:

The horizon (Ancient Greek ὁ ὁρίζων , /ho horídzôn/, from ὁρίζειν , "to limit") is the apparent line that separates earth from sky. It is the line that divides all visible directions into two ca...

If you want to know the distance to the horizon you simply have to know your height of eye. That is the distance that your eyes are off the surface of the water. If you're in ... As you can see from the illustration, because of the curvature of the earth, the higher your height of eye the farther you can see, and vice versa.

A third way to see that the Earth is a sphere is to look at how objects in the distance "disappear" as you get farther away. For example, a 100-foot-tall ship that is 15 miles away is not visible. That's because it is blocked by the curvature of the Earth.

The 'geometric horizon' is the horizon due to the curvature of the surface of the Earth. You can figure out what it is with some simple trigonometry (see either of the ... The optical horizon distance is larger than the geometric one, because the atmosphere bends light around the earth annd allows you to see further.

Estimating distance to horizon ... This problem can be solved by assuming that the earth is a perfect sphere. In fact, if we consider a slice through the centre of the earth, we can treat this problem in two dimensions and therefore consider just a circle.
