Why Do Starlink Satellites Appear in a Line?
Starlink satellites can appear as a line of moving lights when a recently launched group is still close together and sunlit.
New deployments start close together
After launch, satellites from the same deployment can share similar orbits and spacing before gradually spreading out.
Sunlight makes them visible
The satellites are easiest to notice when your sky is dark but the satellites are still high enough to reflect sunlight.
The line fades over time
As satellites raise or adjust orbits, the train becomes less compact and individual objects are harder to see.
Frequently asked questions
Are Starlink trains visible every night?
No. Visibility depends on recent launches, sunlight geometry, your location and weather.
Can a tracker guarantee brightness?
No. Trackers estimate position and pass geometry, but brightness depends on satellite orientation and conditions.
