Stuff in Space — a real-time map of everything orbiting Earth (opens destination in a new tab)

Ever wondered how crowded the sky actually is? Stuff in Space is a real-time 3D map of every satellite, rocket body, and chunk of debris orbiting Earth — red for satellites, blue for rocket bodies, gray for junk. Spin the globe, click any dot to trace its orbit, or search for the ISS. It's beautiful and a little alarming, in the best possible way.
