azmth: real-time satellite tracker
azmth shows more than 15,000 active satellites orbiting Earth on an interactive 3D globe, live. Orbital data comes from CelesTrak and refreshes every 2 hours; positions are propagated in your browser with the SGP4/SDP4 model. Click any satellite for its altitude, orbit, operator country, and real dimensions, and set your location to see exactly when the ISS, Hubble, or a freshly launched Starlink train will pass over you, with time, direction, and elevation. Free, no signup, no ads.

Frequently asked
How many satellites are in orbit right now?
azmth tracks more than 15,000 active cataloged objects, with orbital data from CelesTrak refreshed every 2 hours. Over 10,000 of them are Starlink satellites. See the live statistics page for current counts by country, constellation, and orbit.
How accurate are the positions?
Positions are computed in your browser with the SGP4/SDP4 orbital propagation model from fresh two-line element data, the same math used across the satellite-tracking industry. Pass predictions are typically accurate to within about 30 seconds.
What is a Starlink train?
Right after a launch, a batch of Starlink satellites flies in a tight line that looks like a string of pearls crossing the sky. azmth detects active trains automatically so you can plan to spot one before the satellites spread out.
Is azmth free?
Yes. azmth is free, with no signup and no ads. It runs entirely in your browser and is supported by donations.
