Asteroid 2026 QH3 flew past Earth at 0.95 LD on August 30, 2026

Asteroid 2026 QH3 flew past Earth at 23:20 UTC on August 30, 2026, passing about 365 000 km (227 000 miles), or 0.95 LD, from the center of Earth.

NASA/JPL CNEOS close-approach data give an absolute magnitude (H) of 27.199 but no direct diameter range, while the relative velocity at close approach was 7.25 km/s (4.51 mi/s).

NASA/JPL Small-Body Database (SBDB) lists 2026 QH3 as an Aten-type near-Earth object, with listed orbital elements including an eccentricity of 0.169, a semi-major axis of 0.992 AU, a perihelion distance of 0.824 AU, and an inclination of 10.78°.

The database does not classify 2026 QH3 as potentially hazardous and lists no direct diameter or albedo value for the object.

2026 QH3 was first observed on August 30, 2026. The orbit solution carries a condition code of 7, meaning the orbit is uncertain or preliminary.

Other recent objects in the 1 LD watchlist included 2026 QC3, which flew past Earth at 11:03 UTC on August 24 at 0.10 LD. The same list also included 2026 QA3, which flew past Earth at 06:44 UTC on August 21 at 0.85 LD, and 2026 QR, which flew past Earth at 20:09 UTC on August 18 at 0.13 LD.
