In a collision, the asteroid would only break into smaller fragments, which would then be regrouped by the gravitational force of the nucleus, a study concludes.
An investigation by the Johns Hopkins University of the USA has discovered that asteroids can be much harder to destroy than previously thought. The study published on Monday used a new understanding of rock fracture and a new method of computer modeling to simulate asteroid collisions.
Scientists believed that the larger the object, the easier it would break, because it was highly likely to have flaws or cracks. However, recent findings show that asteroids are stronger and much energy is required to destroy them completely.
"How much energy does it take to break an asteroid into pieces?" Postulated study author Charles El Mir, a doctor in the Department of Mechanical Engineering. According to its model, in an alleged collision the asteroid would only break into smaller pieces that would later be regrouped by the potential effect of the gravity of the nucleus.
That is, the scientists found that the asteroid did not crack completely and the damaged fragments were redistributed over the nucleus, therefore it would take more energy to demolish them.
