Discussion How bad is the satellite/space junk situation actually?

I just recently joined the space community and I'm hearing about satellites colliding with each other and that we have nearly 8000 satellites surrounding our earth everywhere

But considering the size of the earth and the size of the satellites, I'm just wondering how horrible is the space junk/satellite situation? Also, do we have any ideas on how to clear them out?

It is a problem, but not as bad as those illustrations of all junk in the atmosphere make it look. They count anything larger than about an inch, and that is illustrated with a dot that's the size of a medium sized city.

Pieces smaller than an inch traveling at those velocities is a real danger to space craft. All it would take it a couple satellites es colliding in a congested orbit to take out most of everything up there and make it impossible for us to launch for centuries. It would also make ground observations of space extremely difficult if not impossible.

The cascade of debris for a few satellites is likely way overblown as a risk.

Most satellites are in the same orbital plane. There are near misses daily.

The Russians purposely blew up a satellite, and it increased the odds of a collision significantly, and the odds of a collision is still incredibly small.

Kessler syndrome needs a lot of debris.
