In space
Satellite tracker
About 18,000 objects in orbit, from working satellites to debris, placed where their published orbits put them and moving in real time.
What you see
- Everything in CelesTrak’s active catalogue, plus the debris from three break-ups: Fengyun-1C, Iridium 33 and Cosmos 2251.
- Filters for Starlink and other comms satellites, navigation, Earth observation, space stations and telescopes, and military satellites.
- Click one for its name, mission, orbit, altitude, speed and period, the point directly below it, and its next passes over you.
- Follow a satellite and the map stays with it. Share the link and whoever opens it follows it too.
Where the data comes from
- CelesTrakPublished orbital elements for active satellites, bright objects and three debris clouds.
Orbital elements are refreshed from CelesTrak every 2 hours. Positions are worked out in your browser from them, so satellites move smoothly in real time.
Good to know
- Positions are predicted from orbital elements with the SGP4 model, not observed. They drift for satellites that have manoeuvred since the elements were published.
- The groups are picked out by satellite name, so they are approximate.
