Nuclear Bomb Simulations Show Effective Asteroid Deflection Method
En resumen
- Simulations reveal a 3-megaton nuclear explosion could completely blast apart a 100-meter asteroid.
- Burying the bomb 30 meters deep significantly enhances its effectiveness, tripling the change in the asteroid's speed and offering a more precise two-step deflection method.

Researchers simulated a 3-megaton nuclear explosion to assess its capability in deflecting asteroids, finding that burying the bomb significantly increases its effectiveness.
In simulations, a 3-megaton explosion – or around 200 Hiroshima bombs – could completely blast apart an asteroid about 100 metres (328 feet) across, the team reported in the Space: Science & Technology journal in May.
The researchers also found that burying the bomb 30 metres beneath the surface could more than triple the change in the asteroid’s speed compared with a shallow explosion, making it far more effective at pushing the rock off course.
Instead of relying on a high-speed impact at a random spot, the two-step method allows engineers to choose where to bury the bomb and place it much deeper beneath the surface.
