David Yanofsky and Tim Fernholz created an interactive chart showing the weight, national origin and position of more than 1,300 active satellites orbiting the planet Earth. The data was sourced from the Union of Concerned Scientists.
It goes out in bands: there's a cloud in low-earth orbit bulked up with the International Sapce Station and surveillance satellites. Satellite phone networks such as Iridium and Globalstar form conspicuous rings about 800 and 1500 km up. 20km up are the navigation networks GPS and Glonass. 37km up is a mess, with so many geostationary satellites clustered together that they become a rainbow blur in the graphic.
