Is KUIPER-00163 about to reenter?
NORAD 65777 · ~236 km and descending steadily · reentry days to a few weeks
Yes — KUIPER-00163 (NORAD 65777) is one of the lowest active objects still in orbit, currently at about 236 km and descending steadily. At this altitude atmospheric drag is winning, and reentry is days to a few weeks.

How honest is this window?
Be warned: reentry timing is genuinely hard to pin down. Cosmik uses a drag-threshold heuristic — current altitude plus the last 24 hours of decay — not a precise reentry-window solution. Atmospheric density swings with solar activity, so the real window can move by hours or days, and a satellite's exact reentry point isn't known until its final orbits. Treat the window as "something is coming down soon," not a countdown to a place and minute. For the current best estimate delivered automatically, use reentry alerts.
What survives reentry?
Almost nothing, usually. At ~28,000 km/h the atmosphere heats an object until it breaks apart and burns — often visible from the ground as a bright, slow fireball. Only large or dense components (fuel tanks, dense alloys) sometimes reach the surface, and they nearly always fall over ocean or empty land. Read what happens when satellites fall for the full picture, and see how much space debris is in orbit for the bigger context.
Where will it come down?
This satellite circles Earth roughly every 90 minutes, so its ground track covers a wide band of latitudes rather than a single spot. Because the exact reentry time is uncertain, the ground location is too — an hour of timing error moves the point most of the way around the planet.

Frequently asked questions
Is KUIPER-00163 about to reenter?
KUIPER-00163 (NORAD 65777) is at about 236 km as of July 2026 and decaying. Below 260 km atmospheric drag dominates, so reentry is days to a few weeks. This is a drag-threshold estimate, not a precise window — exact timing shifts with solar activity.
What altitude is KUIPER-00163 at?
As of July 2026, KUIPER-00163 is at roughly 236 km, computed by propagating its latest CelesTrak/NORAD orbital elements (TLE) with SGP4. Altitude on this page refreshes as fresh tracking data arrives.
Will KUIPER-00163 hit the ground?
Almost certainly not. The overwhelming majority of satellites and rocket bodies burn up completely on reentry, sometimes as a bright, slow fireball. Only large or dense objects leave fragments that reach the surface, and the odds of debris reaching any given person are vanishingly small.
How can I track KUIPER-00163's reentry?
Watch it move on Cosmik's live 3D satellite tracker, and turn on free reentry alerts to get a push or email when it's predicted to fall. Cosmik updates the prediction as new tracking data comes in.
