padding: 0px; outline: 0px; max-width: 100%; visibility: visible; box-sizing: border-box !important; overflow-wrap: break-word !important;"> 中国天文学会会员、天津市天文学会理事杨婧介绍，绝大多数流星雨的母体都是周期彗星，但双子座流星雨则不同，其母体是3200号小行星法厄同，这是一颗阿波罗型小行星。</section><section style="margin: 0px;

box-sizing: border-box !important; overflow-wrap: break-word !important;"> 和大多数小行星都在火星和木星轨道之间运行不同，法厄同会“越界”跑到地球附近。每年的12月14日前后，地球会接近法厄同的轨道，而其轨道上散落的物质会进入地球的大气层中，与大气摩擦，产生高温，发出强光，进而形成流星雨。由于该流星雨的辐射点在双子座附近，所以被称为双子座流星雨。</section><section style="margin: 0px;
