geminids 解釋
雙子座流星群
  1. This at least accounts for the fact that a particular group of meteoroids shares with its parent comet more or less the same orbit, which can remain relatively unchanged over eons. an immediate consequence is that our earth makes periodic rendezvous with this meteoroid swarm, thereby culminating in a regular display of these celestial fireworks. to name a few, we have the lyrids in april and the geminids in december

    流星雨的成因是地球遇上了一群密集的流星體,一般相信,流星群是由周期性彗星分解出來的物質或由瓦解了的彗核所形成,所以流星群和其母體彗星有大致相同的軌道,由於流星群的軌道頗為固定,所以地球會周期性地穿越這些流星群,形成固定出現的流星雨,例如四月天琴座流星雨十二月雙子座流星雨等。
