WebThe altitude (alt) of an object can lie between 0 o (indicating it is on the horizon) and 90 o at the zenith (or -90 o if it lies below the horizon). The azimuth (az) changes from 0 o for an object due North to 90 o (due East) to 180 o (due South) to 270 o (due West). The horizontal coordinate system is fixed to the Earth and not the stars and therefore, unlike in the … Web5 sep. 2009 · To compute the height of an object visible above the horizon, compute the distance-to-horizon for a hypothetical observer on top of that object, and add it to the real observer's distance-to-horizon.

Web4 feb. 2024 · Studies place the threshold altitude for seeing Earth's curvature at about 35,000 feet. Even at this height, it is difficult to discern the curve as the observer requires a wide-angle of view. Since the distance of the horizon depends on the length of a person, it is possible to see the Earth's curvature while standing on a raised position.
