What is a NORAD ID?
A catalog number used to identify Earth-orbiting objects. Exact IDs give fast lookup.
LIVE SPACE TRACKING
Track satellites live and explore deep space.
Follow real SGP4-propagated Earth satellites, calculate passes from your location, and explore interplanetary spacecraft using NASA/JPL Horizons ephemerides.

Why two tracking systems?
Earth satellites use orbital elements and SGP4. Voyager, JWST and interplanetary missions use JPL Horizons ephemerides.
What is a geometric pass?
A period when an Earth-orbiting satellite is above your geometric horizon. It does not automatically mean the spacecraft is visible to the naked eye.
