[Challenge] If you could right-click the sky...

[Daemian]

I only came out with this imaginary idea;

Assuming the sky texture is up at a distance of 9,000 meters (average height planes fly) from the ground,
we could use the earth's circumference (at its biggest location) to multiply it by the 9,000 mt (no?) and then convert meters to square meters, and square meters to pixels to get the result.


I know, it's all an absurd assumption, but help me get a better formula just for fun. :]
