Primordial asteroids are like giant cushions of space and may be harder to destroy than previously thought

Dust collected from the surface of an ancient, peanut-shaped and “potentially dangerous” asteroid has revealed that some space rocks are much springier and harder to destroy than first thought – raising concerns about Earth’s long-term security.

Analysis of three tiny dust particles collected from the surface of the 500-meter-long debris pile asteroid Itokawa shows that the cosmic wanderer has survived in space for at least 4.2 billion years, despite numerous collisions. This means that not only are asteroids of the same type more likely to make contact with our planet, but hitting them is probably not the best way to deflect or destroy such space rocks.
