  3. The most feature of the orbits of near - earth asteroids ( neas ) is that the semi - major axes of the orbits are nearly equal to that of the earth or the perihelia distances are approximate to or even less than the mean distance between the sun and the earth, thus they could move into inside of the earth ' s orbit, so that they might close approach or even colliside with the earth ( or other planets, such as the venus, the mars, etc. )

    近地小行星軌道的最大特點是其軌道半長徑與地球軌道半長徑相近，或近日距離接近甚至小於日地平均距離，其運動可深人到地球軌道的內部，這將導致該類小行星與地球（還有金星、火星等）十分靠近甚至發生碰撞。
  4. The asteroids are the most important small bodies in the solarsystem, and they mainly lies in the two locations - a main belt between the mars ' s orbit and the jupiter ' s and the near - earth space. the most feature of the orbits of near - earth asteroids ( neas ) is that the semi - major axes of the orbits are nearly equal to that of the earth or the perihelia distances are approximate to or even less than the mean distance between the sun and the earth, thus they could move into inside of the earth ' s orbit, so that they might close approach or even colliside with the earth ( or other planets, such as the venus, the mars, etc. ). the characteristic brings about some difficulties in the numerical research during their orbital evolution, which leads to the failure of the normalization technique in the general removal impact singularities of celestial mechanics methods and the symplectic algorithm which is successfully applied to the investigation in quality. by comparing the computation effects of several common numerical methods ( including symplectic algorithm ), and considering the nature of the movement of the small bodies, the corresponding treatments are provided here to improve the reliability of the computation

    小行星是太陽系最重要的一類小天體，主要分佈在兩個區域；火星和木星軌道之間的一條主帶和近地空間.近地小行星軌道的最大特點是其軌道半長徑與地球軌道半長徑相近，或近日距離接近甚至小於日地平均距離，其運動可深入到地球軌道的內部，這將導致該類小行星與地球（還有金星、火星等）十分靠近甚至發生碰撞.這一特徵給其軌道演化數值研究帶來一些困難，包括天體力學方法中一般消除碰撞奇點的正規化處理以及對定性研究十分成功的辛演算法都將在不同程度上失效.通過對幾種常用數值方法（包括辛演算法）計算效果的比較，根據小天體運動自身的特性，給出了相應處理措施，從而可提高計算結果的可靠性
  5. Near - earth asteroid belt

    近地小行星帶
  6. The mpc is hard - pressed to keep up with the tide of incoming data, especially with a volume of main - belt asteroid observations 100 times as great as that for neos

  7. 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！
  8. Earth - approaching asteroid

    近地小行星

  10. The asteroids are the most important small bodies in the solar system, and they mainly lies in the two locations - a main belt between the mars ' s orbit and the jupiter ' s and the near - earth space

    摘要小行星是太陽系最重要的一類小天體，主要分佈在兩個區域；火星和木星軌道之間的一條主帶和近地空間。
  11. If you explode too close to impact, perhaps you ' ll get hit by several fragments rather than one, so you spread out the area of damage

    如果為了保證效果而使爆炸距離太近，到時候地球可能會被很多爆炸碎塊擊中，就不是單單一個小行星的問題了，這樣反而會使破壞范圍擴大。
  12. 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！
