Asteroid 2026 JH2, a 35-meter wide near-Earth object traveling at 31,000 km/h, passed Earth on May 18, 2026, with only an 8-day warning before its close approach, demonstrating the challenges in detecting and tracking potentially hazardous asteroids that could cause catastrophic impacts similar to the 2013 Chelyabinsk meteor.

Asteroid 2026 JH2: We Had Zero Warning #asteroid #planet #shortsAdded:
Astronomers are tracking a newly-discovered threat that just blindsided our detection systems.
Asteroid 2026 JH2 was spotted just days ago right before crossing inside the orbit of the moon. Measuring 35 m wide, this massive cosmic boulder is the exact same size class as the catastrophic Chelyabinsk meteor. It screamed past Earth at a blistering 31,000 km/h, missing us by a mere 90,000 km. The planetary defense network confirms it safely missed us this time, but what happens when the next one has zero warning?
