ISS Live Tracker
NORAD 25544 tracking in real time
Track the Hubble Space Telescope's real-time orbital position, get visible-pass predictions for your location, and find it in the sky with an in-browser AR finder. About Hubble

Hubble launched aboard Space Shuttle Discovery in 1990 and is jointly operated by NASA and the European Space Agency (ESA). Unlike the ISS, it's an uncrewed observatory — no astronauts live aboard it. It was serviced and upgraded by astronauts on five Space Shuttle missions between 1993 and 2009, and remains in active use for astronomical observation today.
Hubble orbits at roughly 535–540 km altitude, noticeably higher than the ISS's ~400–420 km. Its NORAD catalog number is 20580, cataloged under the short name "HST". This tracker computes its live position via SGP4 propagation over a TLE refreshed regularly from CelesTrak.
Is the Hubble Space Telescope crewed?
No — Hubble is an uncrewed observatory. It was serviced by astronauts on five Space Shuttle missions between 1993 and 2009, but no one is aboard it now or during normal operation.
Is this the same as the James Webb Space Telescope?
No. The James Webb Space Telescope orbits far from Earth near the Sun-Earth L2 point and isn't a near-Earth-orbit object trackable this way. This tracker follows Hubble, which orbits Earth in low orbit similar to the ISS.
The map above shows Hubble's real-time position, computed from official NORAD/CelesTrak orbital data using SGP4 propagation — the same method used by professional satellite-tracking software.
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 Hubble is sunlit but your sky is already dark.
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; Hubble's NORAD ID is 20580.
Yes — use the satellite picker in the header to switch to the ISS, China's Tiangong space station, NOAA 19, or search for any other cataloged satellite by name or NORAD ID.
Yes, it's completely free, requires no account, and can be installed as an app on your phone or desktop.
Scan with your phone's camera — it'll open here with your location and jump straight into AR.
