Un petit ast\u00e9ro\u00efde de la taille d\u2019un camion va passer pr\u00e8s de la Terre dans la nuit de jeudi \u00e0 vendredi, avec l\u2019une des trajectoires les plus proches de notre plan\u00e8te jamais enregistr\u00e9es, mais sans aucun danger, a annonc\u00e9 la Nasa.<\/p>\n\n\n\n
L\u2019ast\u00e9ro\u00efde 2023 BU, r\u00e9cemment d\u00e9couvert par un astronome amateur, passera pr\u00e8s de la pointe sud de l\u2019Am\u00e9rique du Sud vers 0 h 27 GMT vendredi (1 h 27 \u00e0 Paris), pr\u00e9cise la Nasa dans un communiqu\u00e9.<\/p>\n\n\n\n
Il passera \u00e0 seulement 3 600 km de la surface de la Terre, soit beaucoup plus pr\u00e8s que de nombreux satellites g\u00e9ostationnaires orbitant autour de la plan\u00e8te. Mais il n\u2019y a aucun risque que l\u2019ast\u00e9ro\u00efde percute la Terre, souligne l\u2019agence spatiale am\u00e9ricaine. M\u00eame si c\u2019\u00e9tait le cas, l\u2019ast\u00e9ro\u00efde, qui mesure entre 3,5 et 8,5 m\u00e8tres de diam\u00e8tre, se d\u00e9sint\u00e9grerait en grande partie dans notre atmosph\u00e8re, ne faisant retomber potentiellement que quelques d\u00e9bris sous forme de petites m\u00e9t\u00e9orites.<\/p>\n\n\n\n
L\u2019objet a \u00e9t\u00e9 rep\u00e9r\u00e9 samedi depuis un observatoire en Crim\u00e9e par l\u2019astronome amateur Guennadi Borissov, le d\u00e9couvreur de la com\u00e8te interstellaire Borissov en 2019. Des dizaines d\u2019observations ont ensuite \u00e9t\u00e9 r\u00e9alis\u00e9es par des observatoires \u00e0 travers le monde, confirmant l\u2019arriv\u00e9e de 2023 BU.<\/p>\n","protected":false},"excerpt":{"rendered":"
