双子座流星雨是(3200) 法厄同小行星造成的流星雨，这颗小行星被认为是智神星族的小行星 ，有着"岩石彗星"的轨道。它与象限仪座流星雨是少数（目前只知道这两个）不是由彗星造成的流星雨。这个流星雨的流星峰值通常出现在12月13-14日附近，最高强度通常都出现在14日凌晨的2:00-03:00（地方时）。这个流星雨的数量在近几年有逐年增加的现象，在最佳的光学条件下曾经高达每小时120-160颗流星。双子流星雨在1862年首度被观测，而在更早已有英仙座流星雨（36AD）和狮子座流星雨（902AD）的观测纪录。

The Geminids are a meteor shower caused by the object 3200 Phaethon, which is thought to be a Palladian asteroid with a "rock comet" orbit. This would make the Geminids, together with the Quadrantids, the only major meteor showers not originating from a comet. The meteors from this shower are slow moving, can be seen in December and usually peak around December 13–14, with the date of highest intensity being the morning of December 14. The shower is thought to be intensifying every year and recent showers have seen 120–160 meteors per hour under optimal conditions, generally around 02:00 to 03:00 local time. Geminids were first observed in 1862, much more recently than other showers such as the Perseids (36 AD) and Leonids (902 AD).
