Baptis\u00e9 A11pl3Z, il ne pr\u00e9sente pas de risque de collision avec la Terre, a dit le responsable de la d\u00e9fense plan\u00e9taire de l’ESA, Richard Moissl: \u00ab\u00a0Il va voler profond\u00e9ment dans le syst\u00e8me solaire, en passant juste dans l’orbite de Mars\u00a0\u00bb. Evoluant \u00e0 une vitesse estim\u00e9e jusqu’\u00e0 60 km\/seconde, soit plus de 200.000 km\/heure, sa trajectoire \u00ab\u00a0indique qu’il n’est pas en orbite autour du Soleil, mais vient de l’espace interstellaire et va y retourner\u00a0\u00bb. Une confirmation officielle de ses caract\u00e9ristiques est attendue de la part du centre des plan\u00e8tes mineures de l’Union astronomique internationale, qui a enregistr\u00e9 plus de cent observations de l’objet par des astronomes. D\u00e9tect\u00e9 d\u00e8s le 14 juin, il pourrait faire 10 \u00e0 20 km de diam\u00e8tre, ou peut-\u00eatre moins selon M. Moissl. \u00ab\u00a0Il va briller de plus en plus et s’approcher du Soleil jusqu’\u00e0 la fin octobre, et sera encore observable jusqu’\u00e0 l’an prochain\u00a0\u00bb, a-t-il dit. Si sa nature est officiellement confirm\u00e9e, ce serait le troisi\u00e8me objet observ\u00e9 en provenance de l’espace interstellaire. Le premier, Oumuamua, a \u00e9t\u00e9 d\u00e9tect\u00e9 en 2017. Le deuxi\u00e8me, 2I\/Borisov, l’a \u00e9t\u00e9 en 2019.<\/p>\n","protected":false},"excerpt":{"rendered":"
