Advance of the perihelion

近日點前移

Advance of perihelion

近日點前移

Comet giacobini - zinner passed the perihelion on 3 july this year, it is still relatively close to the earth in october. some astronomers predicted that draconids may be worth watching this year

Giacobini - zinner彗星今年在7月3日通過近日點，至10月時與地球尚算接近，因此有天文學家認為今年可能會出現較可觀的天座流星雨。

Draconid meteor shower, associated with comet 21p giacobini - zinner, is not a major meteor showers throughout the year. it approaches the sun every 6. 61years. if the earth is near the comet s perihelion during that period, a stronger meteor shower may occur

它的母體是21p giacobini - zinner彗星，每6 . 61年回歸一次，若當時地球較接近彗星的近日點，便有可能出現較可觀的流星雨。

The numerical computation for the secular variable of the semi - major axis, solar distance at perihelion, orbital periods and longitude of perihelion has been made for fifteen meteor streams by using the solution of gylden - meshcherckii equations

利用g - m型變質量天體軌道根數變化方程的一階和二階解對15個流星群軌道半長軸、近日點距離、軌道周期和近日點經度因太陽質量損失造成的每世紀的長期改變效應做了數值計算，並得出計算結果。

有些小行星體積雖小，但竟然擁有衛星而有些小行星，由於受到其他大行星的強烈攝動，軌道為極狹長的橢圓，遠日點甚至延伸至木星的軌道以外近地小行星則會越過地球的軌道，不時在我們的庭園掠過，偷窺地球的一切，若有天真的登門造訪旄轟！

There are five points in space, called lagrangnian points l1 to l5, where the gravity of the sun and earth exactly cancels out each other. objects residing at these points are in some sort of gravitational equilibrium. more intriguingly, probes can orbit about these lagrangnian points even if no object is present there

以太陽和地球為例，太陽和地球之間的重力在5處不同的地方剛好互相抵消，稱為拉格朗日點l1 - l5 ，物體可以停留在拉格朗日點中而不受重力影響，即使點中沒有物質，物體也可以圍繞拉格朗日點公轉。

More and more researches have shown that most of the intense geomagnetic storms are caused by fast coronal mass ejections in interplanetary space ( icmes ). though the ace satellite can provide solar wind data in almost real time for prediction of geomagnetic storms, the time interval is too short ( shorter than 30 - min ) for effective predictions of major geomagnetic storms

位於拉格朗日點的ace衛星可以提供近實時的太陽風數據，但依據ace衛星太陽風數據進行地磁暴預報，時間的提前量非常有限，對于大地磁暴，這個時間提前量往往不超過30分鐘，這樣的時間提前量對于實際應用來說，是不能令人滿意的。
