Live satellite tracker
Where the satellites above you are right now. Starlinks, space stations, navigation and weather satellites move across the map every few seconds, and a click shows each one’s orbit.
Click any point on the map to see the details. Orbital data: CelesTrak (T.S. Kelso), calculations: satellite.js (SGP4).

How it works
Every satellite has an orbit description published by CelesTrak, based on US Space Force data. From it, your browser works out where the satellite is right now every few seconds using the standard SGP4 model. With fresh data the position matches reality to within a few kilometres.
Satellites in low orbit, like the ISS or Starlinks, circle the Earth in about 90-100 minutes and visibly move across the map from second to second. Navigation satellites take about 12 hours, and geostationary ones go round once a day, which is why they sit still over the equator.
Starlink in orbit right now
According to CelesTrak data from October 25 at 18:19 UTC, 10,640 Starlink satellites are in orbit. That is more than all other active satellites put together.
By orbital inclination
- 53° - the main shell, the most satellites over Europe and the US4,967
- 43° - extra density over mid latitudes3,612
- 70° - coverage further north and south708
- 97-98° - polar orbits, coverage over the poles1,353

FAQ
How many satellites are on the map?
Over 10,000 Starlinks and over 5,000 other satellites: space stations, communications, military, navigation (GPS, Galileo, GLONASS, BeiDou), weather, Earth observation, science and geostationary. Thousands of pieces of debris and spent rocket stages are in orbit too - we leave those out and show only the satellites CelesTrak lists as active.
How often are positions updated?
Positions are recalculated every few seconds in your browser. The orbital data itself is fetched at least once a day, and every 2 hours for Starlink.
What is the line that appears when I click a satellite?
It is the ground track of the orbit: the solid line shows where the satellite flew over the last half orbit, and the dashed line where it will fly during the next orbit.
How can I see a satellite with the naked eye?
The best time is 1-2 hours after sunset or before sunrise, when it is dark where you are but a satellite high above is still lit by the Sun. The ISS is the brightest: it looks like a fast-moving star with no blinking lights.
