Distance to the Horizon - NASA
For an observer standing on the ground with h = 2 metres (6 ft 7 in), the horizon is at a distance of 5 kilometres (3.1 mi). For an observer standing on a hill or tower 30 metres (98 ft) above sea level, the horizon is at a distance of 19.6 kilometres (12.2 mi). See more The horizon is the apparent curve that separates the surface of a celestial body from its sky when viewed from the perspective of an observer on or near the surface of the relevant body. This curve divides all viewing … See more Historically, the distance to the visible horizon has long been vital to survival and successful navigation, especially at sea, because it determined an observer's maximum range of vision and thus of communication, with all the obvious consequences for … See more To compute the greatest distance DBL at which an observer B can see the top of an object L above the horizon, simply add the distances to the … See more From a point above Earth's surface, the horizon appears slightly convex; it is a circular arc. The following formula expresses the basic geometrical relationship between this visual curvature $${\displaystyle \kappa }$$, the altitude $${\displaystyle h}$$, … See more The word horizon derives from the Greek ὁρίζων κύκλος (horízōn kýklos) 'separating circle', where ὁρίζων is from the verb ὁρίζω (horízō) 'to divide, to separate', which in turn derives from … See more Ignoring the effect of atmospheric refraction, distance to the true horizon from an observer close to the Earth's surface is about $${\displaystyle d\approx {\sqrt {2\,h\,R}}\,,}$$ where h is height … See more Due to atmospheric refraction the distance to the visible horizon is further than the distance based on a simple geometric calculation. If the ground (or water) surface is colder than the air above it, a cold, dense layer of air forms close to the surface, causing … See more WebApr 1, 2000 · In miles, the horizon is approximately 3.1 miles away.
