PERIGEE: Satellite Tracker

See what is orbiting above you — and understand what you're looking at.

PERIGEE is a real-time 3D map of everything near Earth: 19,000+ satellites and debris fragments, the ISS, close asteroid approaches, atmospheric fireballs, rocket launches and freshly fallen meteorites. Set your location and SKY shows what is crossing your sky right now and the next pass you can actually see. No accounts, no ads, no tracking.

Positions are calculated from published orbital elements, not live telemetry. An object being overhead is not a promise you will see it: brightness, sunlight, darkness, weather and obstructions all matter. PERIGEE tells you which passes are lit and visible.
