You'd never see a full hemisphere - it's the limit as your distance approaches infinitely far away!

Exactly, Danny -- I wanted to get a sense of how far you needed to get away before the you could see "most" of a hemisphere. I think I always thought the ISS orbited higher than it does, which is why the 3% number was surprising to me. Also the fact that the Blue Marble doesn't nearly show half of the earth was a surprise.

Thanks for posting. This was fantastic!

Hm, can we turn this around? At a given instant, what is the radius of ISS viewability on earth?

I've subscribed to SpotTheStation.NASA.gov in order to receive notifications of ISS visibility. Remarkably, (at least to me,) we've had overflights on three consecutive nights this week, along significantly different tracks each night. This set me to puzzling over how LARGE an area is in view at a given point in time. Any thoughts?
