Explanation: Put on your red/blue glasses and float next to asteroid 101955 Bennu. Shaped like a spinning toy top with boulders littering its rough surface, the tiny Solar System world is about one Empire State Building (less than 500 meters) across. Frames used to construct this 3D anaglyph were taken by PolyCam on the OSIRIS_REx spacecraft on December 3, 2018 from a distance of about 80 kilometers. With a sample from the asteroid’s rocky surface on board, OSIRIS_REx departed Bennu’s vicinity this May and is now enroute to planet Earth. The robotic spacecraft is scheduled to return the sample to Earth in September 2023.

说明: 请载上你的红/蓝眼镜，一起飘浮在贝努小行星（101955 Bennu）之旁。形似旋转玩具陀螺、粗糙表面满布巨石的这颗太阳系小行星，宽度少于500公尺，大小与纽约的帝国大厦相当。用以制作这幅3D立体图的影像，是在2018年12月3日，由OSIRIS_REx航天器的多功能相机于大约80公里之外所拍摄。携带着取自这颗小行星多岩表面样品的OSIRIS_REx航天器，于今年5月告别贝努小行星，目前在返航地球的途中。依据计划，这艘无人航天器将在2023年9月，把样品送回地球。
