En el Centro Nacional de Ciencias Espaciales de China, los investigadores descubrieron en simulaciones que 23 cohetes Long March 5 golpeando simult\u00e1neamente podr\u00edan desviar un gran asteroide de su trayectoria original en una distancia 1,4 veces el radio de la Tierra.<\/p>\n

Sus c\u00e1lculos se basan en un asteroide apodado Bennu, que orbita alrededor del sol, y que es tan ancho como el Empire State Building es alto. Pertenece a una clase de rocas con potencial para causar da\u00f1os regionales o continentales. Los asteroides de m\u00e1s de 1 km tendr\u00edan consecuencias globales.<\/p>\n

Aunque la probabilidad de que Bennu choque con la Tierra es solo de 1 entre 2.700, la destrucci\u00f3n potencial ser\u00eda tan catastr\u00f3fica que los cient\u00edficos ya han empezado a pensar en formas de evitar el lanzamiento de los dados.<\/p>\n

Seg\u00fan las estimaciones actuales, hay aproximadamente un 1 % de posibilidades de que un asteroide de 100 metros de ancho choque con la Tierra en los pr\u00f3ximos 100 a\u00f1os, dijo el profesor Gareth Collins del Imperial College de Londres. \u00abAlgo del tama\u00f1o de Bennu colisionando es unas 10 veces menos probable\u00bb, dijo Collins.<\/p>\n

Alterar la trayectoria de un asteroide presenta un riesgo menor que hacer estallar la roca con explosivos nucleares, que pueden crear fragmentos m\u00e1s peque\u00f1os sin cambiar su curso, dicen los cient\u00edficos.<\/p>\n

\u00abEs posible defenderse de los grandes asteroides con una t\u00e9cnica libre de armas nucleares dentro de 10 a\u00f1os\u00bb, declar\u00f3 el investigador Li Mingtao al\u00a0South China Morning Post.<\/p>\n
