Key Takeaways of Asteroid 2026 JH2 (Updated JPL Solution) (see previous solution report)
- NASA JPL Solution: Solution JPL 9 · Epoch 2461000.5 (2025‑Nov‑21.0 TDB) · SPK‑ID 54629847 · Producer: Otto Matic
- Orbit class: Apollo Near‑Earth Object — semi‑major axis a = 2.4187 au, eccentricity e = 0.5822, inclination i ≈ 6.0°, orbital period 3.76 years (1373.9 days).
- Earth MOID: 0.000734498 au (~110,000 km), meaning the nominal orbit passes well inside the Earth–Moon system, but no impact solution is reported in current JPL risk catalogues.
- Size estimate: Absolute magnitude H = 26.352 → approximate diameter in the 10–25 m range (albedo‑dependent), consistent with a small NEO capable of airburst‑scale effects only in a hypothetical impact.
- Orbit quality: Condition code 4, based on 166 observations over a 10‑day data arc (2026‑05‑10 to 2026‑05‑20), with a normalised RMS of 0.34634 — a moderately well‑constrained, still‑refining orbit.
- Future close approach: JPL SBDB lists a notable Earth encounter on 2090‑05‑14 at a nominal distance of 0.00683 au (~1.0 million km) and relative velocity 9.10 km/s — a close but non‑impacting flyby.
- Risk context: 2026 JH2 is not a Potentially Hazardous Asteroid (PHA) — its size (H > 22) is far below the PHA threshold, and no impact solutions are listed by NASA CNEOS or JPL SBDB.
- Ignore clickbait, sensational videos and news reports claiming that “an asteroid is about to hit Earth” — that is not supported by the data. Follow the evidence, not the entertainment.
