JPL Sentry: Impact Risk Surveillance Table

Automated collision hazard assessment for confirmed Near-Earth Asteroids

Retrieved: Tue, 03 Nov 2026 07:38:26 GMT

JPL Sentry continuously evaluates the orbits of all known asteroids against high-precision planetary ephemerides, calculating potential impact trajectories over the next century. Most entries represent minuscule statistical probabilities (e.g. 1 in 100,000) stemming from slight positional uncertainties that narrow with every new telescope observation.

Torino Scale (0 to 10):

Public impact hazard scale. 0 means No Hazard (normal/zero collision risk). 1 is routine discovery. Values 2–4 merit attention by astronomers. Values 8–10 represent certain collisions.

Palermo Scale (Technical):

Logarithmic scale comparing detected risk to the natural background impact frequency. Values below -2 indicate events of no practical consequence. Values from -2 to 0 merit monitoring. Positive values indicate situations of concern.
