800年以来，木星和土星在今年冬至将第一次这么接近，肉眼看非常清楚 zt yzout2020-11-22 11:27:36

在2020年12月21日晚上日落之后，木星和土星在地球的夜空中的出现将比中世纪以来更加紧密，从而为世界各地的人们提供了一种至高无上的享受，在冬至时响起。

赖斯大学的天文学家帕特里克·哈蒂根说：“这两个行星之间的对准非常罕见，每20年左右发生一次，但是这种结合非常罕见，因为行星之间的距离会非常接近。” “您必须一直回到1226年3月4日黎明之前，才能在夜空中看到这些物体之间的更紧密对准。”

从夏天开始，木星和土星就一直在互相靠近。从12月16日至25日，两者的间隔将小于满月的直径。

Just after sunset on the evening of December 21, 2020, Jupiter and Saturn will appear closer together in Earth’s night sky than they have been since the Middle Ages, offering people the world over a celestial treat to ring in the winter solstice.

“Alignments between these two planets are rather rare, occurring once every 20 years or so, but this conjunction is exceptionally rare because of how close the planets will appear to one another,” said Rice University astronomer Patrick Hartigan. “You’d have to go all the way back to just before dawn on March 4, 1226, to see a closer alignment between these objects visible in the night sky.”

Jupiter and Saturn have been approaching one another in Earth’s sky since the summer. From December 16-25, the two will be separated by less than the diameter of a full moon.
