Asteroid 2026 PC1 flew past Earth at 0.71 LD on August 5, 2026

Asteroid 2026 PC1 flew past Earth at 10:58 UTC on August 5, 2026, passing about 272 000 km (169 000 miles), or 0.71 LD, from the center of Earth.

NASA/JPL CNEOS close-approach data give an absolute magnitude (H) of 27.042 but no direct diameter range, while the relative velocity at close approach was 9.31 km/s (5.78 mi/s).

NASA/JPL Small-Body Database (SBDB) lists 2026 PC1 as an Apollo-type near-Earth object, with listed orbital elements including an eccentricity of 0.557, a semi-major axis of 2.219 AU, a perihelion distance of 0.982 AU, and an inclination of 2.92°.

The database does not classify 2026 PC1 as potentially hazardous and lists no direct diameter or albedo value for the object.

2026 PC1 was first observed on August 7, 2026, and last observed on August 8, 2026. The orbit solution carries a condition code of 8, meaning the orbit is uncertain or preliminary.

Other recent objects in the 1 LD watchlist included 2026 OX3, which flew past Earth at 18:43 UTC on July 27 at 0.65 LD. The same list also included 2026 OW3, which flew past Earth at 18:09 UTC on July 21 at 0.96 LD.
