What percentage of the sky do you envision will be occupied by man made objects?
- Veedrac 7y agoVery small, but that's not a useful measure. For astronomy, remember that bright, fast-moving objects will leave sizable streaks in images that halo a lot[1]. OTOH, intensity varies with time and satellite height. With regards to how much space we have, note that a satellite is taking up an orbit, not a point, and it's a lot harder to fit things in those safely, since they have a tendency to overlap.

- _Microft 7y agoTo put this question into perspective: The Iridium flare which you saw in video [0] so nicely next to what looked like a full-moon was produced by a flat, reflective surface of less than 2m² area at a distance of over 600km. Percentage does not matter here.
