No known near-Earth objects tracked by NASA’s Center for Near-Earth Object Studies or ESA systems carry meaningful impact risk for 2026 at energies sufficient for a 5-kiloton airburst. Sentry risk lists and close-approach data show only small, sub-20-meter objects with negligible probabilities, while historical CNEOS fireball records indicate 5 kt-scale events occur irregularly, averaging roughly once per year from undetected meteoroids. Partial-year 2026 activity, including confirmed tiny impacts like 2026 RW1, remains well below threshold with no model shifts or new detections elevating odds. Ongoing surveys continue to confirm the low baseline hazard from the undetected population.
