Live NASA/JPL CNEOS close-approach intelligence for near-Earth objects. Distances, velocity, estimated size, risk flags, and source links are public-safe and read-only. A close approach is not an impact prediction.

NASA/JPL CAD QueryCNEOS Close ApproachesDiameter is estimated from absolute magnitude H using an assumed albedo range; NASA/JPL CAD may not provide measured diameter for every object.
Risk flag logic: low = routine pass beyond 20 lunar distances; notice = within 20 lunar distances; watch = within 5 lunar distances. This is a public-awareness flag only, not an impact probability calculation.
