Bearing is rank-ordered for visual separation, not true sky position — CAD/Scout summary data does not include right ascension/declination at closest approach. Tap or focus a point for details.

Sentry Impact-Risk Watchlist Official CNEOS Sentry-II data · real Palermo/Torino scale values

Loading Sentry summary…

Sentry monitors objects with a non-zero computed chance of Earth impact over the next ~100 years. Presence on this list does not mean an impact is likely — nearly all listed objects will be removed as more observations refine their orbits. This is the same official data referenced in the ARI methodology disclaimer.

Tip: tap "View Orbit" on any object card below to load it here directly, or look one up by designation. Orbital elements are fetched from JPL SBDB on demand and cached for the session.

No object selected. Search above or open a card's orbit tab.
