12月11日，猎户座飞船从月球外返回，以每秒近11公里的速度进入地球大气层。这是尘埃颗粒速度的一半，当它在12月13日进入大气层时，接近一年一度的双子座流星雨的高峰期，形成了这颗长长的火球流星。当我们美丽的星球每年经过神秘的3200号小行星法厄同的尘埃轨迹时，所有双子座流星的平行轨迹似乎从双子座的一个点辐射出来。在这张中国云南美丽的蓝月亮谷的夜空中，双子座的双星隐藏在左边的树木后面。在山间湖泊平静的水面上，猎户座的星星正在中央附近升起。在月亮升起之前拍摄的，耀眼的火星仍然是场景中最明亮的天体灯塔。

Returning from beyond the Moon, on December 11 the Orion spacecraft entered Earth's atmosphere at almost 11 kilometers per second. That's half the speed of the grain of dust that created this long fireball meteor when it entered the atmosphere on December 13, near the peak of the annual Geminid meteor shower. As our fair planet makes its yearly pass through the dust trail of mysterious asteroid 3200 Phaethon, the parallel tracks of all Geminid meteors appear to radiate from a point in the constellation Gemini. But the twin stars of Gemini hide just behind the trees on the left in this night skyscape from the beautiful Blue Moon Valley, Yunnan, China. Reflected in the still waters of the mountain lake, stars of the constellation Orion are rising near center. Captured before moonrise, dazzling Mars is still the brightest celestial beacon in the scene.
