While harmless due to its small size, the close pass highlights that asteroid detection, though vastly improved, still has blind spots. Data show near-Earth asteroid detections have surged: from 103 small asteroids (under 7 meters) spotted between 2000–2007 to 1,124 between 2017–2026, and 7–20 meter … Continue reading An asteroid passed 428 km from Earth and no one saw it coming
