Story summary

A study indicates iron-rich M-type asteroids may pose a greater risk to Earth by withstanding atmospheric-entry energy.
International scientists conducted the research at CERN's HiRadMat facility to simulate atmospheric-entry stress.
The results challenge the assumption that these asteroids fragment and instead show they can absorb more energy without breaking.
The study calls for ongoing monitoring of Near-Earth Asteroids (NEAs) to better assess their threat level.
