2022 EB5

2022 EB₅ was a small, two-metre Apollo near-Earth asteroid that disintegrated in Earth's atmosphere at 21:22 UTC on 11 March 2022, over the Arctic Ocean southwest of the Norwegian island Jan Mayen. With an atmospheric entry speed of 18 km/s (11 mi/s), the asteroid's impact generated a 4-kiloton-equivalent fireball that was detected by infrasound from Greenland and Norway.^[7][8] A bright flash possibly associated with the event was reported by observers from Northern Iceland.^[8]

Notes

1. 2022 EB₅ is not considered a potentially hazardous object (PHO) due to its small size.^[4] A PHO is defined by having an Earth minimum orbit intersection distance (MOID) of 0.05 AU or less, and having an absolute magnitude of 22 or brighter.^[5]
