I read an article today about a tool called Stuff in Space that shows all of the debris in space. I find it quite interesting.

we must calculate howmany of those are dungs!

Object A-D amuse me...

Wow. This thing is pretty cool.

This is actually very cool and interesting to look at, and I wasn't really big on science in high school 

I checked this thing out. Its pretty amazing that they are able to monitor all that shit up there. 

NASA astrophysicist, Don Kessler, proposed an idea now known as "Kessler Syndrome" wherein the debris in orbit would collide, producing an exponentially increasing number of pieces, with the result being that people would not be able to launch spacecraft or use satellites for 100s of years until enough fell out of orbit.

 

Because of the high speeds of objects involved, even tiny pieces of debris are debilitating to spacecraft:
"They had to replace a window on the STS-7 shuttle because a paint flake roughly a tenth of a millimeter in diameter hit it, puncturing a hole in the windscreen about four or five millimeters across. That was enough to make it unsafe for a relaunch." - VICE interview in 2012.

Damn thats crazy, but it makes sense. I was watching a little documentary/update on the the New Horizons mission to Pluto and beyond and they were saying the same kind of thing. If a cookie crumb hit the satellite at those speeds it would destroy it. Its pretty crazy to think about, something that small having such a huge impact on something exponentially bigger than it.   

Well it has less to do with apparent size and more with inherent energy. like how a bullet dpesn't get fazed by human skin
