Starlink satellite train: How to see and track it in the night sky

A vast fleet of Starlink satellites orbits Earth, providing internet coverage on a global scale. On a clear night, you may be able to catch a glimpse of a few satellites in this megaconstellation as they crawl across the sky. And if you're lucky enough to see them shortly after deploying, you might even see them appear as a "Starlink satellite train."

While the ever-growing satellite armada is a menace to astronomical observations, it can provide an interesting target for skywatchers if you know when and where to look.

Appearing as a string of bright lights in the sky, Starlink trains can look rather "otherwordly" and have prompted numerous UFO-sighting reports when they first took to the skies. But the long lines of lights are only visible shortly after launch. Once the satellites climb to their operating altitude of 340 miles (550 kilometers) they disperse and are far more difficult to differentiate against the backdrop of stars, though a timelapse photograph will pick them out easier.

The megaconstellation developed by the private spaceflight company SpaceX may grow to as many as 42,000 satellites in orbit, according to the science news website NASA Spaceflight. As of May 31, 2023, there are 4,198 Starlink satellites in orbit, of which 3,542 are operational according to astronomer Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics who tracks the constellation on his website. Given the high numbers of regular Starlink launches (sometimes multiple times a week), there is ample opportunity to set your sights on catching a glimpse of the infamous "Starlink train". 

Though it should be noted that Starlink satellites are not as visible nowadays compared to when they first appeared. This is due to efforts such as the Starlink VisorSat program which aim to darken the satellites so as to not interfere as much with astronomical observations.

Why can we see Starlink satellites? Do they have lights?

We can see Starlink satellites only when they reflect sunlight; they do not possess lights of their own. 

The vast and ever-increasing numbers of satellites from SpaceX and other private space companies, such as OneWeb, suggest that light pollution and other issues stemming from these megaconstellations may continue, and advocates have called for greater regulations from government agencies.

Can you spot them when they deobit?

If Starlink satellites fail to make orbit, they then return to Earth in dramatic fashion, burning up as they go. This happened on Feb. 4, 2022, when a freshly launched batch of Starlinks encountered the effects of a big geomagnetic storm. They were sent crashing back to Earth over the coming days and a remarkable video captured some of the space debris burning up over Puerto Rico on Feb. 7, 2022.
