Situ\u00e9e dans la constellation du Cancer, elle pr\u00e9sente un diam\u00e8tre apparent de 45,3 sec d’arc et une magnitude de -2,5 ce qui en fait l’objet le plus brillant du ciel nocturne apr\u00e8s la Lune <\/a>et V\u00e9nus<\/a>.<\/p>\n

L’image ci-dessus (r\u00e9alis\u00e9e avec un zoom) nous montre Jupiter <\/a>dans la soir\u00e9e du 7 f\u00e9vrier : on distingue deux satellites du c\u00f4t\u00e9 est de la plan\u00e8te (Callisto <\/a>-magnitude 5,6- et Ganym\u00e8de magnitude 4,6) alors qu’\u00e0 l’ouest Europe <\/a>et Io se confondent tr\u00e8s pr\u00e8s du disque jovien.<\/p>\n

Cette ann\u00e9e le p\u00e9rig\u00e9e de Jupiter co\u00efncide avec le passage de la Terre dans le plan \u00e9quatorial de la plan\u00e8te, l’occasion d’observer le ballet des quatre satellites d\u00e9couverts en 1610 par Galil\u00e9e, qui vont s’\u00e9clipser et s’occulter mutuellement. Il se produira 442 ph\u00e9nom\u00e8nes de ce type entre le 1er septembre 2014 et le 20 juillet 2015 !\u00a0Il y a quelques jours astronomes amateurs et professionnels avaient pu assister \u00e0 un triple transit de satellites<\/a> devant le disque jovien.<\/p>\n
