2025 FA₂₂, sometimes shortened to FA22, is a near-Earth (NEO), potentially hazardous asteroid (PHA). It is a member of the Apollo group orbiting at a distance of 1.49 AU with an orbital eccentricity of 0.41 and an inclination of 7.62°.

Physical characteristics

The asteroid has an estimated diameter between 130 and 290 meters. Studies on the polarimetry and albedo of 2025 FA₂₂ is consistent with it being a M-type asteroid.

Close approach

The asteroid had a close approach with Earth on 18 September 2025 at a distance of two lunar distances. It was among the largest near-Earth objects at such proximity which prompted an International AsteroidWarning Network (IAWN) rapid-response campaign. Although early orbital solutions of 2025 FA₂₂ predicted a possible impact in the year 2089, follow-up astrometric observations later ruled out the possibility.
