Orbital Traffic: Space Tracker

Space has traffic. Watch it move.

Orbital Traffic puts more than 19,000 tracked objects on a live 3D globe: the International Space Station, crewed capsules, fresh Starlink trains, navigation and communications satellites, debris and near-Earth asteroids. Every position is computed on your phone from the latest orbital data.

No ads. No account. Nothing about you leaves your device.

PASS ALERTS
Get a heads-up 10 minutes before the ISS or a Starlink train crosses your sky. Alerts fire only for passes worth stepping outside for: high in the sky, in sunlight, and never in the middle of the night. One a day at most. Tap the bell on any pass to make sure you get that one.

SEE IT FROM THE GROUND
Open the ISS or a train and find out when it passes over you next: what time, where to look, how high it climbs, and a sky chart of its path.

STARLINK TRAINS
Freshly launched batches are spotted automatically and lit up on the globe while they're still flying in a line, with their length, spacing and next good pass from where you are.

TODAY IN SPACE
Launches as they happen, dockings and undockings, re-entries and crew changes, all in one feed. Been away a while? Orbital Traffic shows you what you missed.

YOUR SKY
Tap once to see what's above you right now. The notable ones are named and explained, and the big constellations are folded into a line each.

THE CREW AND THE FLEET
See who's living aboard the ISS and China's Tiangong station, and follow Dragon, Soyuz, Shenzhou, Progress, Cygnus and Tianzhou from launch through docking to landing.

THOUSANDS OF OBJECTS, EXPLAINED
Search the catalog for hand-written profiles on 2,800+ notable objects: who built it and why it's up there. Live telemetry on everything: altitude, speed, orbit and the ground below it.

BEYOND EARTH ORBIT
77 near-Earth asteroids on their real orbits around the Sun, with their next close approach. Ask where Voyager or New Horizons is and get its distance right now.

SAVE AND SHARE
Star favorites, keep a watchlist, and make a shareable card of anything in orbit.
