Scientists Warn Giant Asteroid Is Actually Swarm of Particles, Nearly Impossible to Destroy

Researchers have found that some asteroids that are largely made from small pieces of rubble could be very difficult to deflect if one were to ever hurtle towards Earth, a terrifying finding that could force us to reconsider our asteroid defense strategies.

It’s an especially pertinent topic considering NASA’s recent successful deflection of asteroid Didymos by smashing its Double Asteroid Reduction Test (DART) spacecraft into it last year, a proof of concept mission meant to investigate ways for humanity to protect itself from asteroid threats.

By analyzing asteroid particles collected by Japanese Space Agency’s Hayabusa 1 probe, which visited the 1,600-foot “rubble pile” asteroid Itokawa back in 2005, the researchers suggest the remote asteroid is far older than previously thought.
