The map above shows the ISS's real-time position, computed from official NORAD/CelesTrak orbital data using SGP4 propagation — the same method used by professional satellite-tracking software.
The ISS orbits at roughly 27,600 km/h (about 17,150 mph), circling the Earth once every 90 to 93 minutes, at an altitude of approximately 400–420 km (250–260 miles). For the full numbers, see how fast the ISS travels and how high it orbits.
Enter your location (or tap “Use my location”) in the Next Pass panel for upcoming visible pass times, including elevation, duration, and a cloud-cover forecast. A pass is visible when the station is sunlit but your sky is already dark. Not sure when to look? Check if the ISS is visible tonight, or browse pass times for 33 major cities.
A NORAD ID (Satellite Catalog Number) uniquely identifies every tracked object in Earth orbit. A TLE (Two-Line Element set) encodes a satellite's orbit and is refreshed regularly from CelesTrak; the ISS's NORAD ID is 25544. Learn how ISS tracking works if you want the full picture.
Yes — use the satellite picker in the header to switch between the ISS, China's Tiangong space station, the Hubble Space Telescope, and the NOAA 19 weather satellite.
