Asteroid Castalia Impact Simulation
|
This visualization shows Castalia, a larger-than-average asteroid, being hit by a house-sized rock traveling at 5 kilometers per second. Lasting merely a second, the collision approximates the force of the Hiroshima atomic bomb. Using nuclear weapons has been proposed for breaking up, or at least diverting, asteroids headed towards Earth. Simulations show that such an impact will fracture a solid asteroid, but, later, gravity will reassemble the pieces.
