Another thing that comes up often, is the question "why don't we ever see any other satellites and space debris that are supposedly orbiting the Earth?" I have my thoughts on this, namely, that I'm not sure we should expect to see any because of how small they are in comparison. But we CAN see satellites from the ground on a clear nighttime sky where there's minimal light pollution in the form of reflected light, right? So why don't we ever see the same thing in these full disc Earth images? And also on that topic, why don't we see stars in them?
