Asteroid 2026 JN4 impacts Earth over the Arafura Sea
Sat May 16 7:43 am
A small asteroid designated 2026 JN4 entered Earth’s atmosphere between Australia and Papua New Guinea at 13:44 UTC on May 15, 2026, after ESA’s Meerkat and JPL’s Scout systems identified a high Earth-impact probability from a short observation arc. This is now the 12th predicted Earth impactor and the first since December 3, 2024. Meter-scale asteroids of this size and velocity usually disintegrate high in the atmosphere.
