NASA descubre ocho asteroides peligrosos

La Administración Nacional de la Aeronáutica y del Espacio (NASA) de Estados Unidos anunció el descubrimiento de ocho asteroides que podrían se una amenaza potencial para la Tierra, esto a través de la misión Neowise (Explorador Infrarrojo de Campo Amplio para Sondeo de Objetos Cercanos a la Tierra).

De acuerdo a la NASA, Neowise, en su primer año en funciones, ha logrado clasificar un total de 439 objetos cercanos al planeta, también llamados NEOs, que es un término utilizado para designar a todo tipo de asteroide o cometa que se acerque de manera relativa a nuestro mundo, de los cuales 72 eran desconocidos para los científicos.

La sonda, que en un inicio era llamada Explorador Infrarrojo de Campo Amplio para Sondeo (WISE), fue lanzada en 2009 y desactivada en 2011 cuando su misión original fue desactivada, aunque fue puesta en operaciones en 2013 y renombrada con el fin de apoyar a los astrónomos en la búsqueda de objetos celestes cercanos a la Tierra.

Cabe mencionar que durante el año pasado, Neowise tomó cerca de 5.1 millones de imágenes infrarrojas y midió más de 19 mil asteroides, además que tras un análisis, la NASA reconoció 439 como NEOs, de los cuales solamente ocho representan un peligro potencial para el planeta.

«Los datos arrojados por Neowise nos dan una mejor comprensión de los orígenes de los objetos cercanos a la Tierra, que proceden de diferentes partes del cinturón principal de asteroides entre Marte y Júpiter o de las poblaciones de cometas más helados», aseveró el investigador principal adjunto de la misión del Laboratorio de Propulsión a Chorro de la agencia estadounidense, James Bauer.
