  1. For example, if there is a planet orbiting around the neutron star, it will wobble a little and the pulses will come a little early or late. we can then deduce the mass and the radius of the orbit of the planet from the arrival time of the pulses. this is how the first extrasolar planet is discovered

    例如假若有一顆行星圍繞一顆中子星運行，它會令中子星出現搖動，引致脈沖的間隔變長或短，由此我們根據脈沖周期的變化，可推斷出行星的質量和軌道半徑，這亦是天文學家找出第一顆地外行星時所用的方法。
  2. The minor planet … please find the minimum possible value of the eccentricity of the asteroid ' s orbit

    此句可否換個說法： 「請給出這顆小行星可能的最小的軌道離心率數值。 」
  3. It is also used for the difference between the observed position of an object ( minor planet or comet ) and the position calculated from an orbit

  5. Some asteroids, despite their small size, possess satellites of their own. a handful of others suffer serious perturbations by major planets and travel in highly eccentric orbits, which can send them well beyond the orbit of jupiter. the so - called near - earth asteroids cross the earth s orbit and make occasional close calls to our home planet

    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！
  6. It due to enter the moon ' s orbit in about a week ' s time and should bring back pictures of the planet surface by the end of november

  8. Not only is it unusally large ( 40 percent more massive than pluto ), but it orbits neptune backward, the only large moon to orbit in the opposite direction of its host planet ' s spin

    它不僅有非同一般的大小（比冥王星還大40 % ） ，而且它還繞著海王星向後運轉，是唯一一顆運轉軌道方向與主行星相反的大衛星
  9. It takes the man - made satellite 48 hours to orbit the planet around

    這個人造衛星花費了48個小時繞行星一周。
  10. If you just read the official definition, then even jupiter and earth are not planets because there are asteroids around their orbits and hence they do not clear the orbits. similarly, neptune is not a planet because pluto crosses the orbit of neptune

    從表面看來，即使木星地球也不是行星，因為在它們的軌道內亦有不少小行星，它們並未能清空軌道附近的其他天體，同一道理，由於冥王星會橫過海王星的軌道，所以海王星理應亦不附合作為行星的條件！
  11. This planet, unlike the other planets in our solar system, has an elliptical orbit and moves clockwise rather than counterclockwise

    這顆行星，不同在我們太陽系的其他行量，是橢圓形軌道，順時針方向移動，而不是逆時針。
  12. Under proposed international astronomical union definitions, two planets that orbit each other around a barycenter between them are a binary planet

    根據國際天文學會的定義提出兩個行星軌道周圍的重心在彼此之間是雙行星系統。
  13. While the death star was forced to orbit a target world before firing its superlaser and annihilating the planet, the galaxy gun fired giant, high - yield explosive projectiles into hyperspace

    與死星在超級激光聚能並開火毀滅目標行星之前要首先進入並環繞該行星軌道不同，銀河之槍直接向超太空發射出巨大的，高能量爆炸性的發射彈。
  14. Maya priests observed the positions of the sun, moon, and stars. they made tables predicting eclipses and the orbit of the planet venus

    1971年的今天，美國宇宙飛船水手九號順利進入火星的計劃軌道飛行，成為首架環繞另一顆行星飛行的宇宙飛船。
  16. Scientists know they are there, because the rings would not survive without them : the dust grains that compose jupiter ' s rings are too small to remain in orbit for long, before drifting into space or falling into the planet

    科學家們知道它們就在那兒，因為沒有它們就沒有光環：組成木星光環的塵埃顆粒太小了，在飄入太空或墜入行星前沒辦法在軌道上停留很久。
  17. 1 a planet is a celestial body that is in orbit around the sun, has sufficient mass for its self - gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium nearly round shape, and has cleared the neighbourhood around its orbit

    1 .行星是指符合以下特性的天體： a在圍繞著太陽的軌道上運行b有足夠質量以產生引力達至流體靜力平衡的形狀近似球形及c已使其軌道附近清空。
  18. 2 a dwarf planet is a celestial body that is in orbit around the sun, has sufficient mass for its self - gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium nearly round shape, has not cleared the neighbourhood around its orbit, and is not a satellite
