The curvature of the horizon is easily seen in this photograph, taken ... to an
altitude of approximately 2640 km above the Earth's surface. ... + distance^2)-
radius, equivalent to distance^2/R*...
The radius of the Earth is R, and the observer's eye is a height h above the point
... If h is in meters, that makes the distance to the geometric horizon 3.57 km ...
because the relative curvature of the ray and the Earth's surface is all that matters
In an earlier question on the curvature of the Earth Harley to showed that the
earth ... this distance to his horizon, where the line of sight is tangent to the earth's
Using the Pythagorean theorem, that calculates to an average curvature of 7.98
inches per mile or approximately 8 inches per mile. The distance to the horizon ...
... large body of water is not actually flat at all -- it follows the curvature of the
Earth. ... where "height above surface" is in feet and "distance to horizon" is in
