10,000+satellites
Static snapshot from 2 October 2026; the current model replaces it after the page loads.
Why the number changes
Launches add satellites, atmospheric re-entry removes objects and operational status changes. Classified or poorly tracked objects may be absent from public catalogues, so no public number is perfectly complete.
