What else to look for beyond satellites.
Reading the catalogue…
Tell us when you saw it and which way it was moving — our identifier checks every tracked satellite, the big constellations, and even aircraft overhead to work out what it was.
🔭 IDENTIFY WHAT YOU SAW →No telescope needed. Here's everything you need to know.
A satellite looks like a steady, bright dot moving smoothly across the sky — like a slow-moving plane but with no blinking lights. It takes 2–5 minutes to cross from horizon to horizon.
They're brightest during twilight (just after sunset or before sunrise) when the sky is dark but the satellite is high enough to still catch sunlight.
Starlink satellites sometimes appear as a "train" of dots in a line shortly after launch, before they spread out to their operational orbits.
Satellite: Steady light, moves smoothly, no blinking. Crosses the sky in 2–5 minutes. May fade in or out as it enters Earth's shadow.
Plane: Has blinking red/green/white lights. Usually you can hear it if it's close enough to see clearly.
Star/Planet: Doesn't move (or moves very slowly over hours). Stars twinkle, planets don't.
Everything runs live in your browser from public orbital data — open it, see what's overhead, go outside.
Real-time satellite positions on a 3D globe. Updates every 2 seconds — you can watch them move.
"Look Northwest, halfway up" — not coordinates. Tells you exactly where to point your eyes.
Calculates your twilight window — tells you which passes are actually visible, not just overhead.
