How to watch satellites tonight
Satellites are easiest to see shortly after sunset or before sunrise, when the sky above you is dark but the satellite, hundreds of kilometres up, is still lit by the Sun. They look like steady points of light that cross the sky in a few minutes without blinking.
Pick your location and SkyPass Tonight lists every predicted pass for the coming night: when it appears, where to look, how high it climbs and when it fades. Passes higher than 40° above the horizon are the easiest to spot.
Frequently asked questions
Why does a satellite suddenly disappear?
It has entered Earth's shadow. It is still in orbit, but it no longer reflects sunlight.
How accurate are the times?
Usually within a minute. Orbits change slightly every day, so the orbit data is refreshed whenever the site is rebuilt.
Do I need a telescope?
No. The ISS, Tiangong and Starlink trains are visible to the naked eye; binoculars help with fainter satellites.
