Starlink satellite train: how to see and track it in the night sky (2025)

The "Starlink satellite train" has become a captivating sight for skywatchers, offering a glimpse of the future of global internet coverage. This dazzling spectacle occurs shortly after SpaceX launches a new batch of its Starlink satellites — part of the megaconstellation that provides high-speed internet worldwide. On clear nights, you may spot these satellites as they streak across the sky, resembling a string of bright, evenly spaced lights.

While these satellites concern astronomers due to their impact on observations, they’ve captured the public's imagination. The Starlink satellite train is often mistaken for UFOs because of its otherworldly appearance. However, this striking formation is short-lived; as the satellites ascend to their operational orbit at 340 miles (550 kilometers), they disperse and blend into the starry backdrop. If you’re hoping to spot this celestial procession, timing is everything — so keep an eye on launch schedules and visibility forecasts.

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 March. 28, 2025, there are 7,135 Starlink satellites in orbit, of which 7,105 are working, according to Astronomer Jonathan McDowell, 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".

However, it should be noted that Starlink satellites are not as visible nowadays compared to when they first started to be deployed back in 2019. This is due to efforts such as the Starlink VisorSat program which aims to darken the satellites so as to not interfere as much with astronomical observations.

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.

How often can you see a Starlink satellite train?

Can you spot Starlinks when they deorbit?

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.
