This is just amazing how technology works. Here is an image of earth with a plot of all satellites around our tiny planet. I found Galaxy 19 in this plot as well, the tiny dot in blue.
Here is the link:
And that doesn't include all the millions of pieces of "space junk" -- dead satellites, upper rocket stages, nuts, bolts, astronaut gloves, and other chunks of old space hardware -- orbiting the planet. It's starting to become a real hazard out there to the ISS and other functioning spacecraft/satellites. There are ongoing concerns about collision potential.
It's definitely a potential collision problem, especially in low earth orbit (where the space station is).
No issue with blocking the Sun, though. The graphic display makes it look like the whole sky is getting filled up with stuff, but that's just the effect of the graphic -- on the scale shown, each dot would be hundreds of miles across, rather than a few feet across. And many of the chunks of space debris are only inches across.
As far as cleanup goes, there are efforts underway. Here's one:
The challenge with sending this stuff to the Sun is achieving escape velocity from Earth. Lots of energy would be required to do that, whereas very little energy would be required to trigger a de-orbit burn and have the stuff disintegrate in Earth's atmosphere.
Since the beginning of human history, people have understood that the sun is a central part of life as we know it. It's importance to countless mythological and cosmological systems across the globe is a testament to this. But as our understand of it matured, we came to learn that the sun was...
