Each December the Geminids meteor showers appear in the night sky. The 2021 showers are currently active until Dec. 17 and will peak on the night of Dec. 13 into the morning of Dec. 14, making those hours the best time for viewing the meteor shower.

每年12月,双子座流星雨都会出现在夜空中。2021年流星雨将持续到12月17日,并将在12月13日晚至14日上午达到高峰,因此这段时间是观赏流星雨的最佳时间。

The Geminids are caused by debris from a celestial object known as 3200 Phaethon, whose origin is the subject of some debate. Whatever the nature of Phaethon, observations show that the Geminids are denser than meteors belonging to other showers, enabling them to get as low as 29 miles above Earth’s surface before burning up. Meteors belonging to other showers, like the Perseids, burn up much higher.

双子座流星雨是由3200法厄同天体的碎片造成,该天体的起源一直存在争议。 无论法厄同的性质如何,观测表明双子座流星雨比属于其他流星雨的流星密度更大,使它们能够在燃烧之前低至地球表面上方29英里处。而属于其他流星雨的流星,如英仙座流星,则在更高处就开始燃烧。

The Geminids can be seen by most of the world but are best viewed by observers in the Northern Hemisphere.

双子座可以被世界上大多数人看到,但最好的观测地点在北半球。
