Meteors.ai Impact Watch
meteors.ai never computes its own impact predictions. Every single figure displayed across Impact Watch comes directly from official NASA and JPL surveillance pipelines, is clearly labeled with its primary source and retrieval timestamp, and is explained in plain human language. If an official source is down or unreachable, we state data unavailable—never a guess, never a simulation, and never an unverified claim.
New Candidates
/impact-watch/new
Objects detected in the past few hours or days on the Near-Earth Object Confirmation Page. NASA/JPL Scout evaluates unconfirmed observations in near-realtime to alert telescopes worldwide if an object warrants urgent follow-up.
Monitored Risk Table
/impact-watch/list
Confirmed asteroids with computed, non-zero impact probabilities over the next century. Shows official Torino & Palermo scales with plain-language definitions, historical tracking trends, and objects removed from the Sentry database.
Atmospheric Fireballs
/impact-watch/fireballs
Sensor recordings of real atmospheric impacts worldwide. Explores bolide burst energy in kilotons with familiar documented comparisons, altitude, velocity, and a phone-friendly 2D map free of overlapping labels.
Understanding Planetary Defense Telemetry
How does Scout differ from Sentry?
Scout monitors unconfirmed discoveries from the past hours or days with short observation arcs. Its impact ratings identify objects needing immediate follow-up. Sentry tracks confirmed asteroids with well-determined orbits, computing gravitational perturbations and potential impact solutions across decades to centuries into the future.
Why are objects removed from Sentry?
NASA/JPL publishes removed objects with designation and removal date without per-object rationale. See NASA/JPL's explanation of the Sentry list for details on the monitoring table and removed objects.
