Thinking about this a bit. One second before an impact, an object 3 meters across and 15 km away would be too small to resolve with the human eye. It would grow from a dot to hitting you in one tick of a clock. Orbital speeds are *fast*.

I enjoy relaxing in the hammock after sundown and spotting satellites. Sometimes I see two at once crossing paths or seemingly in a chase. Can you tell me what's going on with this one? Is it an atmospheric effect? Glad you're on the job, Phil. Thanks!pic.twitter.com/MpTsINdE9R

Did it look this way by eye? And as it a satellite or meteor? IOW was it moving slowly or very rapidly?

What will be lost if they collide and malfunction?

Both are long deactivated, But the debris from a collision would be substantial.

If that were in low atmosphere between two aircraft ATC would be having words with the pilots.

Also, these are some *old* objects - I'm surprised anything launched in '67 is still up there

It will surprise no one who knows the astrophysicist Jonathan McDowell (
@planet4589) to learn that he has posted a cogent series of tweets detailing this potential collision between IRAS and POPPY 5B.https://twitter.com/planet4589/status/1221947817255743488 …

Ouch! Somehow I failed to post the FIRST tweet in Jonathan's thread. My apologies. Try this:https://twitter.com/planet4589/status/1221939151295197187 …

I wonder how often this happens. I'm actually surprised this doesn't happen more often with everything up there.

See also "big sky" theory. Humans suck at estimates of how much space there is when there's three dimensions instead of two
