5月将出现水星凌日火星冲日等天象|火星|凌日_新闻资讯

　　原标题：5月天宇将上演“水星凌日”“火星冲日”等天象

　　新华社天津4月30日电(记者 周润健)5月的天象剧场，好戏连台。宝瓶座厄塔流星雨、天琴座厄塔流星雨、水星凌日、火星冲日等天象将先后登场。

　　有着著名的哈雷彗星“血统”的宝瓶座厄塔流星雨，将于5月6日4时左右达到极盛，届时，每小时将有数十颗流星划过夜空。

　　“今年该流星雨极大时恰逢无月夜，我国感兴趣的公众可在6日黎明前的1－2个小时进行观赏和观测。”中国天文学会会员、天津市天文学会理事史志成提醒说。

　　宝瓶座厄塔流星雨的高峰期刚刚过去两天，小流量的天琴座厄塔流星雨将于5月8日“接棒”。

　　“这个流星雨活跃期比较短，今年极大期预计在8日和10日。”史志成提醒说，“虽然该流星雨极大时的天顶流量仅为个位数，但好在这几天都是无月夜，幸运的天文爱好者在观测时或许能有所收获。”

　　作为本年度最值得期待的天象之一，5月9日将发生极为罕见的水星凌日，届时，我国中、西部地区可见带凌日落，且越往西见凌时间越长。

　　史志成介绍说，凌日是内行星经过日面的一种天文现象。水星和金星的绕日运行轨道在地球轨道以内，称内行星。它们距离太阳比地球近，在运行过程中有时经过太阳与地球中间，在地球上的人们可观测到一个小黑圆点在日面缓缓移动，这就是凌日现象。

　　有“战神”美誉的火星5月22日将上演冲日表演。所谓火星冲日，就是指火星运行到了与太阳黄经度相差180°的位置，即太阳、地球、火星几乎在一条直线上。

　　“日落时火星会从东方升起，亮度为－2.1等，日出时于西方落下，整夜可见。冲日前后是观测火星的较佳时机。”史志成提示说。(完)
