Orbital debris, the ISS, moon and sun

Here’s an animation showing the accumulation of debris in near earth orbit due to human activity since 1957. It does look very cluttered but remember the articles aren’t to scale.

And where is all the junk coming from (click on image to get more detail – thanks to Michæl Paukner’s photostream): Continue reading

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.
