How far up do you have to go to see the Blue Marble
Clearly you have to be higher than the International Space Station
, but you don't have to go all the way to the moon
Googling yields lots of info about seeing the curvature of the Earth, but that's not what I'm looking for. I want to know how far you have to go to see the whole Earth as a circle.
