Tiny NEO 2026 RC — ~0.76 LD flyby Sep 3; close approach, not an impact

Origin Lane: neoNASA JPL CNEOS, Pasadena, California

NASA’s Center for Near-Earth Object Studies close-approach table lists newly observed object 2026 RC at a nominal Earth distance of 0.00194305463978998 astronomical units on 3 September 2026 at 23:05 TDB (CAD field is TDB, not UTC; t_sigma_f 00:09). That is about 0.76 lunar distances (~290,700 km). Relative velocity is 6.24388618588521 km/s; absolute magnitude H = 29.14. JPL SBDB classifies it as a NEO, not a PHA, Aten-class, with first observation 2026-09-02. The Sentry API summary reports cumulative Palermo scale −10.88 with impact probability on the order of 2×10⁻⁹ for a far-future virtual impactor (listed around 2079) and an estimated diameter near 5 meters — negligible risk framing, and unrelated to the September 3 close approach itself. This is a close approach, not an impact forecast. There is no official Earth impact location for the flyby.

Assumed place pin at JPL/CNEOS (Pasadena) — no Earth impact location; close approach ≠ impact. Source map

NASA/JPL SBDB Close Approach Data API for 2026 RC

CAD distances and times are from the official NASA/JPL SBDB Close Approach Data API. A Palermo scale near −11 and impact probability near 10⁻⁹ describe a negligible far-future virtual-impactor entry on Sentry, not a prediction that 2026 RC hits Earth on 3 September 2026.

Doom Signals does not invent miss distances, diameters, or impact corridors. Close approach ≠ impact.

  • Object: 2026 RC (Aten NEO, not PHA)
  • CAD: 2026-Sep-03 23:05 TDB at ~0.76 LD
  • Assumed place pin: JPL/CNEOS Pasadena — no Earth impact location

Why it matters

Fresh Sep 2 discovery with an official sub-lunar (~0.76 LD) flyby on Sep 3 — distinct from boarded OH3/NT2/QB2/QQ1. Cataloged close approach for a tiny Aten; not an impact forecast.
