This is an amazing short video detailing the progress of "space junk" and man made objects orbiting the earth. I have placed this in the UFO forum
because let's face it, some of our unidentified sky sightings undoubtedly can be sourced to the incredible amount of artificial satellites orbiting
the planet. That aside, the video documents a timeline of space junk that culminates in a baffling amount of present-day satellites.
