Japanese Probe Sets Record With 400-Meter Asteroid Flyby
August 1, 2026
A Japanese space agency probe passed just 400 meters, roughly 1,312 feet, from a near-Earth asteroid this month, the closest approach ever recorded for an asteroid flyby mission. The Japanese space agency confirmed the milestone, which places Japan again at the front of close-proximity asteroid operations. The maneuver marks the second time Japan has set the record in this category. The agency previously executed the Hayabusa missions, establishing a track record of close asteroid encounters.
