Low Earth Orbit (LEO).

An orbit around Earth with an altitude of approximately 160 to 2,000 km above mean sea level. Used for most Earth-observation satellites, the International Space Station (ISS at ~400 km), Starlink (~550 km operational), and short-duration crewed missions. LaunchDetect tracks every active satellite in LEO via the CelesTrak TLE catalog.

LEO is the most-populated orbital regime, with ~10,000 active satellites as of 2026. Orbital period at LEO is typically 90-100 minutes.
