  3. It is because the plane of the lunar orbit does not coincide with the plane of the earth s orbit. so, for most full moons, the moon is either south or north of the orbital plane of the earth

    原來月球的公轉軌道平面和地球的公轉平面並不一致，因此在滿月時，月球通常不是在地球軌道平面之南，就是在其北，難得會進入位於軌道平面的地影內，所以大部分滿月都不會出現月食。
  4. Once in orbit, two of the themis spacecraft will circle earth about one - sixth the distance to the moon while the other two circle half way to the moon

    一旦進入軌道， themis計劃的2枚衛星將在1 / 6地月距離上環繞地球運動，而其他兩枚將在1 / 2地月距離運動。

    引擎再度燃燒大約五分鐘，將宇航員從低地球軌道推送到前往月球的路上去。
  6. The roche limit for the earth is a small fraction of the radius of the moon's orbit.

    地球的洛希極限相當于月球軌道半徑的一小部分。
  7. It ' s rare because the moon is usually either above or below the plane of earth ' s orbit

    但這種情形難得發生，因為月球通常在地球軌道平面的上方或下方運動。
  8. As another example the center of mass of the earth and moon moves in an approximately circular orbit around the sun.

    作為另一個例子，地球和月亮的質心就是在一個繞太陽的近似的圓軌道上運行。
  9. Selecting the image elements of earth and moon centers as observed quantity, measurement noise model and observed equations of autonomous navigation system are built up. the spacecraft orbit is determined by using the recursive weighted least square based on ud factorization

    在奔選取地心和月心像素作為觀測量，建立了符合實際情況的量測噪聲模型和自主導航系統的觀測方程，並利用基於ud分解的遞推加權最小二乘演算法估計了奔月探測器的軌道參數。
  10. This magnetotail extends more than one million kilometers past the earth, well beyond the orbit of the moon

    這條磁尾向外延伸超過100萬公里，遠遠超越了月球繞地球的公轉軌道。
  11. " apollo 17 astronauts, in orbit around the moon, photographed a crescent earth rising in the lunar sky.

    在環繞月球的軌道中，阿波羅17號的宇航員拍下了正從月亮的天空升起的月牙般的地球。
  12. Besides, by reason of its long distance from jupiter, the earth can maintain a rather circular orbit. also the gravitation of the moon can stabilize the tilt of the rotational axis of the earth, thus restricting climatic fluctuation within a narrow range

    另外，地球因與木星保持距離，能維持著一個幾近圓形的軌道，加上月球的引力穩定了地球自轉軸傾斜的角度
  13. Since then, space technology has become a burgeoning industry : in 1961, yuri gagarin became the first human in history to orbit the earth. in 1969, man set foot on the moon, a celestial body more than 380, 000 kilometres away

    自此，太空科技發展一日千里1961年，尤利加加林成為第一位環繞地球飛行的太空人1969年，人類首次踏足遠在380 ， 000公裡外的月球。
  14. An impact （ on the mars ） capable of ejecting a fragment of the martian surface into an earth - intersecting orbit is even less probable than such an event on the moon, in view of the moon ' s smaller size and closer proximity to earth

    一個能夠把活性表面的碎片射入地球交叉軌道的碰撞發生的可能性甚至小於這種事件在月亮上發生的可能性，考慮到月亮更小的尺寸及其與地球接近的程度。
  15. This falling keeps the moon in its orbit. similarly, the earth and other planets fall to the sun constantly

    地球和其他行星也是這樣不斷向太陽落下，才會以現時的軌道繞日運行。
  16. There would be no way to repair and upgrade this telescope, though ? it would be placed in an inaccessible orbit around the so - called second lagrangian point, where the earth, the sun and the moon orbit one another while remaining in the same position relative to each other

    然而韋博望遠鏡將無法得到維修和更新，因為它將被設置在一個無法達到的軌道（在所謂的第二拉格朗日點附近，在一點上地球、太陽和月亮相互圍繞運轉，但卻保持相對不變的位置） 。
  17. That ' sdespite the fact that the distance changes minute by minute because the moon is in an elliptical 28 - day orbit ranging from 220 000 to about 252 000 miles from earth

  18. If the equivalence principle were violated, the moon ' s orbit around the earth would appear skewed, either towards or away from the sun

    如果等效原理遭到違背，月球圍繞地球公轉的軌道將會出現偏斜? ?靠近或是遠離了太陽。
