Starlink Tracker
Real-time positions of Starlink satellites on a rotating 3D globe, computed in your browser from public orbital data (TLE) with the SGP4 model.
Location is only used with your explicit permission: your browser will ask for authorization before "Find satellites above you" works. Your coordinates are processed only on your device (to compute which satellites are above your horizon) and are never sent to or stored on our servers.
What is Starlink?
Starlink is the broadband internet satellite constellation developed by SpaceX, the aerospace company founded by Elon Musk. Since 2019, SpaceX has been launching thousands of relatively small satellites into low Earth orbit (LEO) to provide internet connectivity in rural or remote areas without cable infrastructure, as well as services for maritime navigation, aviation, emergency response and, more recently, direct-to-cell connectivity for ordinary smartphones.
Unlike traditional geostationary satellites (positioned at about 35,786 km altitude), Starlink’s low orbit greatly reduces connection latency, at the cost of needing a much larger number of satellites for continuous coverage. The live counter above shows how many are currently catalogued as active — part of a constellation planned to grow to tens of thousands of units in the coming years.

FAQ — Starlink Tracker
Where does the data come from?
From CelesTrak, a public catalogue of TLE (Two-Line Element) orbital data updated regularly. This page caches the Starlink TLE set for a few hours and computes current positions live in your browser.
What is a TLE?
A Two-Line Element set is a compact text format describing a satellite orbit at a given time (epoch). Combined with the SGP4 model it lets you compute the satellite position at any later time, with accuracy that decreases the further you get from the epoch.
Does this tool show when a satellite is visible to the naked eye?
No. The globe shows the geometric position of every satellite right now, and the "above you" search shows which ones are geometrically above your local horizon. Naked-eye visibility also requires a dark sky and the satellite still lit by the Sun: for precise pass times use a dedicated tool such as Heavens-Above or Find Starlink.
Is this an official SpaceX / Starlink service?
No. This is an independent, informational visualization built on public orbital data. It is not affiliated with, endorsed by, or connected to SpaceX or Starlink.
How many Starlink satellites are currently in orbit?
The number changes continuously with new launches and re-entries. This page shows a live count based on the public CelesTrak catalogue — see the "Catalogued satellites" statistic above.
At what altitude do Starlink satellites orbit?
Most Starlink satellites operate in low Earth orbit (LEO), at altitudes of roughly 340 to 550 km, split across several orbital shells with different inclinations — much lower than traditional geostationary satellites (about 35,786 km).
Why do I sometimes see a line of moving lights in the sky (the Starlink train)?
Right after launch, a batch of Starlink satellites still travels closely together before gradually spreading out and reaching its operational orbit. During this phase, shortly after sunset or before sunrise, they can appear as a regular line of moving bright dots — the so-called "Starlink train".
Does Starlink cause light pollution problems for astronomy?
It is a debated topic in the astronomical community: the large number of reflective satellites can disturb observations and long-exposure astrophotography, especially soon after launches. SpaceX has introduced measures such as anti-reflective coatings and sun visors to reduce their brightness.
