Satellite Tracking Spectacular

Ever wondered how many satellites there are orbitting Earth? Wonder what the pattern looks like? Well, go visit J-Track 3D at NASA. It only shows 500, not all of them, but the 3-D display is zoomable and rotatable. The "ring" at Geostationary orbit is quite pronounced, then within that there's the Cats-Cradle of GPS satellites, then finally the hundreds of satellites in LEO (Low Earth Orbit).
