About Satellite Re-Entries
Hundreds of satellites and pieces of space debris re-enter Earth's atmosphere every year. Most burn up harmlessly, but larger objects — spent rocket bodies, defunct satellites, and space station cargo modules — can survive re-entry and reach the ground. This tracker monitors satellites in their final days of orbital decay, below 240 km altitude where atmospheric drag accelerates rapidly.
Re-entry predictions use Two-Line Element sets (TLEs) from Space-Track.org, updated multiple times per day. Countdown timers show predicted decay time when available. Orbital events flag sudden eccentricity changes that may indicate a breakup, collision, or deliberate deorbit maneuver.
