2025 FA22 (also 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°.[2]
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.[3][4]
Close approach
The asteroid had a close approach with Earth on the 18th of 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.[3][4]
