Near-Earth Object (NEO) and PHA Asteroid Close-Approach Report: September 26, 2026

Catalogued Earth close-approaches across a 7-day window from the NASA NeoWs feed (JPL small-body solutions; cached at source). This bulletin is a catalogue report, not a live CNEOS CAD/Scout stream. Live Multi-watch CAD/Scout/Sentry tracker.

On September 26, 2026 (UTC), screening of the NASA NeoWs catalogue resolves 39 near-Earth object close approaches across the report window. The single closest encounter is 2018 SP2, passing at approximately 5.01 lunar distances (1,927,097 km) with a relative velocity near 14.3 km/s. No listed object is on an impacting trajectory.

DETERMINISTIC analysis · same clock as the feed

The window contains 39 catalogued Earth close-approaches (8 on the report date, 31 in the forward outlook). The nearest listed geometry is 2018 SP2 at 5.01 LD (non-PHA), relative velocity 14.3 km/s. 5 objects in the window are flagged potentially hazardous (size and MOID criteria, not this week's miss distance). No listed object is on an impacting trajectory in this catalogue.
