Look out!

This is scary stuff. Look at all that space junk. I guess it’s a matter of resolution. But it must be quite a job keeping track of it all.


Each dot represents a bit of known space junk that’s at least 4 inches (10 cm) orbiting Earth. Note the distinctive outer ring, known as a geostationary orbit, where weather and communication satellites orbit at the same rate that the Earth turns, allowing them to remain over a single spot on Earth at all times. The concentration of dots obscuring Earth in the center of the image represent debris in low-Earth orbit. In total, some 19,000 manmade objects this size or bigger orbit Earth as of July 2009; most are in low-Earth orbit. Countless smaller objects are also circling the planet.
