在太阳系中存在着来自地球之外的人造天体,这已不是什么奇闻了。1961年,在巴黎天文观测台工作的法国学者稚克·瓦莱意外地发现了一颗运行方向与其他卫星相反的地球卫星,这颗来历不明的卫星被命名为“黑色骑士”。随后,世界上有许多天文学家按稚克·瓦莱提供的精确数据,也发现了这颗环绕地球逆向旋转的独特卫星。1981年苏联的一家天文台也证实了“黑色骑士”的 It is no surprise that there are man-made objects in the solar system that come from outside the Earth. In 1961, the French scholar who had worked at the Astronomical Observatory in Paris, Wuer Vale, accidentally discovered a terrestrial satellite that runs opposite the other satellites. The unknown satellite was named “Black Knight.” Subsequently, many astronomers in the world, according to the precise data provided by Chirac Valerie, also found this unique satellite that rotates counter-clockwise around the Earth. A Soviet observatory in 1981 also confirmed “Black Knight”
