With all these pics from the Artemis, including ones from the earth; why don’t we see any satellites and other stuff that circles the earth? Are they too small to see at these distances? Still, i would expect some of them to at least glint in the sunlight.
Update; thanks for confirming it’s indeed that they are too small to see. Also, i didn’t think of the pixels, good point.

They are way to small, space is BIG.
Mind-boggling, one has said.
I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.
The biggest satellite is like what, 30 metres across with solar panels?* Earth’s diameter is ~13 000 km, that’s 400 000 times larger. A satellite might as well be a grain of sand.
* Biggest unmanned artificial satellite that I could find info on is the Hubble telescope, which is 13m long; its solar panels are not longer than the telescope tube.
If you get some place you can see the starry sky, sometimes you can pick out satellites. It might look like a small bright star moving across the sky in a straight line.
Sometimes they’re just aircraft. I’m not really up on my astronomy, so I’m sure some of them could be other celestial bodies. But I’m pretty sure a satellite appears to move faster than a planet and slower than a shooting star
Yes, i see them frequently. Planes often have blinking lights and fly lower. And shooting stars are already gone in the blink of an eye. Also, i have an app -Stellarium - that, if in doubt, shows whether they’re satellites.
Because space is huge and satellites are tiny. It’s like why you can’t see a football on the ground from a commercial airliner
They’re tiny relative to space. They don’t produce any light so on non-backlit shots, you wouldn’t see them unless the sun reflected off a surface the right way.
This guy explains it perfectly Dave McKeegan
the pics don’t have enough pixels to see them at this distance. they are small fractions of the pixels.
