ISS tracker — the Space Station, live in 3D
The International Space Station circles Earth 16 times a day at 28,000 km/h. Cosmik tracks it live: its exact position this second on a 3D globe, its ground track for the next orbits, and the minute it will cross the sky over your city. Open the live ISS tracker →
What the ISS tracker shows
- Live position — the station as a real moving object over Earth, updated every second from official orbital data.
- Next passes over you — when the ISS rises over your location tonight, from which direction, and how high it climbs.
- Onboard view — ride along with the station and see Earth from 420 km up.
- Free pass alerts — push, email or Telegram a few minutes before every visible pass.
How to spot the ISS tonight
The ISS looks like a bright, fast, steady star crossing the whole sky in a few minutes — brighter than any star, with no blinking lights. The best sightings happen shortly after sunset or before sunrise. Check tonight's ISS pass times for your city (550+ cities), or read our guide on how to track and photograph the ISS.
Behind the tracker
Cosmik propagates the station's latest two-line elements (published from US Space Force radar tracking via CelesTrak) with the standard SGP4 model — the same math professionals use, accurate to about a kilometer. Alongside the ISS you can track 20,000+ other satellites, watch Starlink swarm the sky, or get alerts before every rocket launch.
FAQ
Where is the ISS right now?
The International Space Station orbits Earth at about 420 km altitude, completing one orbit every ~92 minutes at 28,000 km/h. Cosmik's ISS tracker computes its live position every second from the latest published orbital elements (TLEs propagated with SGP4), so the map shows exactly where the station is at this moment and the path it will trace next.
When can I see the ISS from my city?
The ISS is visible from any given city several evenings and mornings per month, when it crosses your sky while still lit by the Sun against a dark background. Cosmik computes tonight's passes for your exact location — direction, start time, maximum elevation and duration — for over 550 cities worldwide or from your device's position.
Is this ISS tracker free?
Yes. Cosmik is a free ISS tracker that runs in any browser — no app to install, no account, no paywall. The live 3D view, pass predictions and alerts are all free.
Can I get an alert before an ISS pass?
Yes — enable free ISS alerts on Cosmik and you'll get a push notification, email or Telegram message shortly before the station rises over your location, so you never miss a visible pass.
