Asteroid 2025 AL2 approaches at 2.2 lunar distances; ~100-metre diameter, 12.4 km/s

Observed

Asteroid 2025 AL2, an object estimated at approximately 100 metres in diameter, passed Earth at a closest distance of roughly 2.2 lunar distances — where one lunar distance equals the average gap between Earth and the Moon, approximately 384,400 kilometres. The asteroid was travelling at a speed of around 12.4 kilometres per second relative to Earth at the time of closest approach.

Forecast

No impact risk is associated with this pass. Asteroid 2025 AL2 followed a well-characterised trajectory that carried it safely beyond Earth, and no models currently project any future close approach of concern within established monitoring windows.

Interpretation

At 2.2 lunar distances, this asteroid passed at roughly 845,000 kilometres from Earth — more than twice the distance to the Moon. While that may sound remote in everyday terms, it is considered a notably close encounter in planetary science, and objects of this size and proximity are routinely tracked by space agencies as part of standard near-Earth object monitoring programmes. An asteroid of around 100 metres would cause significant regional destruction if it were ever to strike, which is why such passes receive scientific attention even when, as in this case, there is no danger.

Flarient Analysis

Asteroid 2025 AL2 represents a moderate-interest close approach that falls well within the threshold used by planetary defence researchers to flag objects for detailed observation. Its 100-metre diameter places it in a size category capable of causing serious localised damage, reinforcing the value of continuous sky survey programmes. Flarient's assessment is that this event warrants public awareness as a reminder of the active near-Earth object environment, but carries no cause for concern.
