Asteroid 2026 SZ2 flew past Earth at 0.06 LD on September 20, 2026

Asteroid 2026 SZ2 flew past Earth at 21:19 UTC on September 20, 2026, passing about 21 000 km (13 000 miles), or 0.06 LD, from the center of Earth.

NASA/JPL CNEOS close-approach data give an absolute magnitude (H) of 30.548 but no direct diameter range, while the relative velocity at close approach was 7.99 km/s (4.97 mi/s).

NASA/JPL Small-Body Database (SBDB) lists 2026 SZ2 as an Apollo-type near-Earth object, with listed orbital elements including an eccentricity of 0.465, a semi-major axis of 1.856 AU, a perihelion distance of 0.991 AU, and an inclination of 11.92°.

The database does not classify 2026 SZ2 as potentially hazardous and lists no direct diameter or albedo value for the object.

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 SB, which flew past Earth at 04:52 UTC on September 15 at 0.33 LD. The same list also included 2026 RO39 and 2026 RB39, which passed at 07:44 UTC on September 14 and 02:29 UTC on September 17, respectively, at 0.66 LD and 1.00 LD.
