Asteroids’ irregular shapes complicate nuclear-blast deflection as a short-notice planetary-defense option

Bookmark this story

A stand-off nuclear blast could redirect a hazardous asteroid on short notice, using the burst’s X-ray pulse rather than an atmospheric shock wave, according to the article. But asteroids’ irregular shapes and uneven composition make their response difficult to predict, complicating the use of this approach for planetary defense.

Briefing

What Hype is tracking

  • The proposal presents a potential rapid-response option for deflecting a dangerous asteroid, but the article identifies asteroid shape and nonuniformity as major sources of uncertainty.
  • Predicting how an irregular body responds to an X-ray pulse is central to assessing whether this intervention could reliably change its trajectory.
