（华盛顿2日综合电）美国太空总署（NASA）的“新视野号”探测器，于周二（1日）元旦日最接近离地球65亿公里的小行星Ultima Thule，拍下并传回这个小行星的首个影像。从照片可见，Ultima Thule外形像个保龄球瓶。

NASA负责这次任务的科学家证实，新视野号已于美国东岸时间周二凌晨零时33分，在Ultima Thule的3500公里外掠过。由于与地球相距实在太远，信号至同日早上10时30分左右才传回NASA。

从传回的模糊影像判断，这个像保龄球瓶的小行星长约32公里，阔约16公里，像螺旋桨般旋转，也可能是两个靠近的星体围绕对方运行。

更清晰的彩色影像最快于周三（2日）传回地球，而历来最高清的影像料于2月才传到。NASA的科学家收到信号后，喜呼“我们的太空船状况很好”，并庆祝完成这个创下太阳系最远探索距离的任务。

任务负责人斯特恩大感振奋，称十分喜欢这个2019年的喜讯，庆祝后睡了一顿好觉。
