Near-Earth Object (NEO) and PHA Asteroid Close-Approach Report: October 2, 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 October 2, 2026 (UTC), screening of the NASA NeoWs catalogue resolves 40 near-Earth object close approaches across the report window. The single closest encounter is 2015 TS238, passing at approximately 4.72 lunar distances (1,813,910 km) with a relative velocity near 15.8 km/s. No listed object is on an impacting trajectory.

Astrophyzix analysis · same clock as the feed

The window contains 40 catalogued Earth close-approaches (5 on the report date, 35 in the forward outlook). The nearest listed geometry is 2015 TS238 at 4.72 LD (non-PHA), relative velocity 15.8 km/s. 1 additional pass inside 5 LD. 3 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.
