獅子座流星雨一般是什么時間出現?

獅子座流星雨每年11月14日至21日,尤其是11月17日左右,都有一些流星從獅子座方向迸發出來,大概方位是在東偏北一點,水平高度40度左右的天空區域,這就是獅子座流星雨。

據江蘇省天文學會介紹：著名的獅子座流星雨于11月14日～21日處于活躍期，并將于11月18日4時50分達到極盛。該流星雨的每小時理論天頂流量為10～100顆流星，但真正能被愛好者觀測到的流星一整晚也就數十顆左右
。
18日正值農歷八月二十八，一輪殘月基本上不會影響觀測。
因此是一次難得的觀測流星雨的好機會。

獅子座流星雨在每年的什么時候出現?

獅(shi)子(zi)座(zuo)流(liu)(liu)星雨(yu)每(mei)年11月(yue)14日(ri)(ri)至21日(ri)(ri)，尤其是11月(yue)17日(ri)(ri)左右，都有一些流(liu)(liu)星從獅(shi)子(zi)座(zuo)方(fang)向(xiang)迸發(fa)出來，這就是獅(shi)子(zi)座(zuo)流(liu)(liu)星雨(yu)。獅(shi)子(zi)座(zuo)流(liu)(liu)星雨(yu)產生的(de)原因(yin)是由于(yu)存(cun)在一顆(ke)叫坦(tan)普爾塔(ta)特爾的(de)彗星。

這(zhe)顆彗(hui)星(xing)(xing)繞太陽公(gong)轉，同時(shi)，它(ta)不斷拋散(san)自身的(de)(de)(de)(de)物質，就象(xiang)灑農藥那樣，在它(ta)行進的(de)(de)(de)(de)軌(gui)道上散(san)下許多小微(wei)粒(li)，但這(zhe)些小微(wei)粒(li)分布并不均勻(yun)。有的(de)(de)(de)(de)地(di)(di)(di)(di)方稀薄，有的(de)(de)(de)(de)地(di)(di)(di)(di)方密集(ji)，當(dang)地(di)(di)(di)(di)球(qiu)遇上微(wei)粒(li)稀薄地(di)(di)(di)(di)方，出(chu)現的(de)(de)(de)(de)流(liu)星(xing)(xing)就少，遇到(dao)密集(ji)的(de)(de)(de)(de)地(di)(di)(di)(di)方，出(chu)現的(de)(de)(de)(de)流(liu)星(xing)(xing)就多。這(zhe)些小微(wei)粒(li)很容易受各種因素的(de)(de)(de)(de)影響而慢慢飄散(san)，但在彗(hui)星(xing)(xing)回(hui)歸(gui)時(shi)，地(di)(di)(di)(di)球(qiu)會(hui)經過它(ta)近期釋放出(chu)的(de)(de)(de)(de)顆粒(li)稠密區。地(di)(di)(di)(di)球(qiu)上的(de)(de)(de)(de)人們(men)便會(hui)看到(dao)大規模的(de)(de)(de)(de)流(liu)星(xing)(xing)雨(yu)。今年(nian)(nian)3月坦(tan)普爾塔(ta)特爾彗(hui)星(xing)(xing)再次回(hui)歸(gui)，所以今年(nian)(nian)或明年(nian)(nian)獅子(zi)座將出(chu)現景(jing)象(xiang)壯觀的(de)(de)(de)(de)獅子(zi)座流(liu)星(xing)(xing)雨(yu)。由于坦(tan)普爾特爾彗(hui)星(xing)(xing)的(de)(de)(de)(de)周(zhou)(zhou)期為(wei)33.18年(nian)(nian)，所以獅子(zi)座流(liu)星(xing)(xing)雨(yu)是一個典型的(de)(de)(de)(de)周(zhou)(zhou)期性流(liu)星(xing)(xing)雨(yu)，它(ta)的(de)(de)(de)(de)周(zhou)(zhou)期約為(wei)33年(nian)(nian)。

世界上最大的流星雨 是什么星座?

獅子座流星雨
獅子座流星雨每年11月14日至21日，尤其是11月17日左右，都有一些流星從獅子座方向迸發出來，這就是獅子座流星雨。獅子座流星雨產生的原因是由于存在一顆叫坦普爾?塔特爾的彗星。
這(zhe)顆(ke)彗(hui)(hui)星(xing)(xing)繞太陽公轉，同時，它(ta)(ta)(ta)不(bu)斷拋散自身的(de)(de)物質(zhi)，就象灑農(nong)藥那樣，在它(ta)(ta)(ta)行進的(de)(de)軌道上(shang)散下許多(duo)(duo)小微(wei)(wei)粒(li)，但這(zhe)些小微(wei)(wei)粒(li)分布并不(bu)均勻。有的(de)(de)地(di)(di)方(fang)(fang)稀薄(bo)，有的(de)(de)地(di)(di)方(fang)(fang)密集，當地(di)(di)球遇(yu)上(shang)微(wei)(wei)粒(li)稀薄(bo)地(di)(di)方(fang)(fang)，出現(xian)的(de)(de)流(liu)星(xing)(xing)就少，遇(yu)到密集的(de)(de)地(di)(di)方(fang)(fang)，出現(xian)的(de)(de)流(liu)星(xing)(xing)就多(duo)(duo)。這(zhe)些小微(wei)(wei)粒(li)很容易受各種(zhong)因素的(de)(de)影響而慢慢飄(piao)散，但在彗(hui)(hui)星(xing)(xing)回歸時，地(di)(di)球會(hui)(hui)經過它(ta)(ta)(ta)近期(qi)釋放出的(de)(de)顆(ke)粒(li)稠密區。地(di)(di)球上(shang)的(de)(de)人們便會(hui)(hui)看到大(da)規模的(de)(de)流(liu)星(xing)(xing)雨。今年(nian)3月坦(tan)普爾?塔特(te)爾彗(hui)(hui)星(xing)(xing)再次回歸，所以今年(nian)或明年(nian)獅(shi)子(zi)座將(jiang)出現(xian)景象壯觀的(de)(de)獅(shi)子(zi)座流(liu)星(xing)(xing)雨。由于坦(tan)普爾?塔特(te)爾彗(hui)(hui)星(xing)(xing)的(de)(de)周期(qi)為33.18年(nian)，所以獅(shi)子(zi)座流(liu)星(xing)(xing)雨是一個典型的(de)(de)周期(qi)性流(liu)星(xing)(xing)雨，它(ta)(ta)(ta)的(de)(de)的(de)(de)周期(qi)約為33年(nian)。...

2001年有大型的什么流星雨

這個你想要哪(na)方面(mian)的(de)(de)(de)(de)講(jiang)解呢？那(nei)(nei)次(ci)(ci)(ci)我(wo)去觀測了，我(wo)終(zhong)身難(nan)忘那(nei)(nei)次(ci)(ci)(ci)的(de)(de)(de)(de)壯觀場面(mian)。獅子(zi)座(zuo)流星(xing)雨(yu)的(de)(de)(de)(de)母彗星(xing)是(shi)(shi)坦(tan)普(pu)爾(er)(er)——塔特爾(er)(er)彗星(xing)。彗星(xing)每次(ci)(ci)(ci)回歸太陽附近的(de)(de)(de)(de)時候就(jiu)在太陽風的(de)(de)(de)(de)作用(yong)下剝離(li)出一(yi)些物質(zhi)(zhi)，當地球與(yu)這些物質(zhi)(zhi)相遇時，就(jiu)會(hui)發生流星(xing)雨(yu)。只要流星(xing)都(dou)是(shi)(shi)從一(yi)個輻射點出來的(de)(de)(de)(de)，就(jiu)叫做(zuo)流星(xing)雨(yu)，輻射點在哪(na)個星(xing)座(zuo)，就(jiu)叫什么(me)星(xing)座(zuo)的(de)(de)(de)(de)流星(xing)雨(yu)。每年可稱為(wei)流星(xing)雨(yu)的(de)(de)(de)(de)有(you)大約40個。但絕(jue)大部(bu)分都(dou)是(shi)(shi)一(yi)小(xiao)時只有(you)幾顆。象2001年獅子(zi)座(zuo)的(de)(de)(de)(de)這次(ci)(ci)(ci)是(shi)(shi)可遇而不(bu)可求(qiu)的(de)(de)(de)(de)。坦(tan)普(pu)爾(er)(er)——塔特爾(er)(er)彗星(xing)的(de)(de)(de)(de)回歸周期是(shi)(shi)33-34年，所(suo)以(yi)獅子(zi)座(zuo)流星(xing)雨(yu)的(de)(de)(de)(de)大爆發周期就(jiu)是(shi)(shi)33-34年。但形成(cheng)流星(xing)雨(yu)的(de)(de)(de)(de)物質(zhi)(zhi)質(zhi)(zhi)量(liang)都(dou)很小(xiao)，稍微受到(dao)(dao)引力擾動就(jiu)會(hui)改變到(dao)(dao)達地球的(de)(de)(de)(de)時間。所(suo)以(yi)下次(ci)(ci)(ci)大爆發的(de)(de)(de)(de)時候我(wo)國未(wei)必處于最(zui)佳觀測地區(qu)，而且到(dao)(dao)時候月相如(ru)何也不(bu)知(zhi)道(dao)，月光(guang)會(hui)不(bu)會(hui)成(cheng)為(wei)干擾也很難(nan)說，所(suo)以(yi)我(wo)看(kan)過2001年那(nei)(nei)次(ci)(ci)(ci)后(hou)就(jiu)沒指望這輩子(zi)還(huan)能看(kan)到(dao)(dao)第二次(ci)(ci)(ci)這么(me)壯觀的(de)(de)(de)(de)。真的(de)(de)(de)(de)是(shi)(shi)“星(xing)隕如(ru)雨(yu)”啊！...
