Chinese satellite came within 200m of Starlink-6079, travelling at ~17,400mph.

    LEO is not a permanent orbit. There’s atmospheric drag. I believe Starlink satellites deorbit in 5 to 10 years. Oldest ones are already falling back to earth (burning in the atmosphere)

      While true, they continuously replenish the ones that fall back to earth. I wouldn’t be surprised if their current launch pace is higher than the amount falling out of orbit. That’s not even mentioning the impact they have on ground-based astronomy.

      This is a problem as well. As the satellites deorbit they vaporise, leaving aluminium oxide nanoparticles (and other metallic gases, volatiles etc) in the atmosphere, destroying ozone and building up over decades.
      So it’s not just the light pollution, or the ruining of ground based astronomy. Or even the dangerous amount of clutter polluting LEO, making spaceflight even more risky. Starlink is bad news for the environment, but it’s to be expected since we’ve seen how carelessly spacex have destroyed the ecosystem in Texas.
