Asteroid 2026 UA1 will fly past Earth at 0.58 LD on October 23, 2026

Asteroid 2026 UA1 will fly past Earth at 17:36 UTC on October 23, 2026, passing about 222 000 km (138 000 miles), or 0.58 LD, from the center of Earth.

NASA/JPL CNEOS close-approach data give an absolute magnitude (H) of 27.91 but no direct diameter range, while the relative velocity at close approach was 9.49 km/s (5.90 mi/s).

NASA/JPL Small-Body Database (SBDB) lists 2026 UA1 as an Apollo-type near-Earth object, with listed orbital elements including an eccentricity of 0.316, a semi-major axis of 1.136 AU, a perihelion distance of 0.777 AU, and an inclination of 5.92°.

The database does not classify 2026 UA1 as potentially hazardous and lists no direct diameter or albedo value for the object.

2026 UA1 was first observed on October 20, 2026, and last observed on October 21, 2026. The orbit solution carries a condition code of 7, meaning the orbit is uncertain or preliminary.
