  1. One astronomical unit equals the distance from the earth to the sun.

    一天文單位等於從地球到太陽的距離。
  2. Recall that one astronomical unit is the average distance between the sun and the earth

    來表示，一天文單位即太陽和地球的平均距離請參閱
  3. It dwells in the kuiper belt at about 42 au away and moves around the sun every 288 years 1 astronomical unit the distance between the earth and the sun, about 150 million kilometers

    據初步計算，這顆天體距離地球約4 2個天文單位個天文單位太陽和地球的距離，即約15億公里，運行一周需時288年。
  4. 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。
  5. 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
  6. While the earth seems to be knowingly keeping its distance from the sun, it is really only centrificating

    地球好象要和太陽保持距離，實際上是離心力的作用。
  7. And this measurement, in turn, would allow scientists to estimate not only the distance between earth and the sun but also the scale of the entire solar system

    天文學家已經由克卜勒的行星運動定律知道所有行星和太陽的相對距離，所以他們能夠由金星視差計算出太陽視差，讓科學家得以估計地球與太陽的距離，以及整個太陽系的尺度。
  8. Its distance from this star is only 5 % of that between the earth and the sun

    這顆行星每隔幾天就能繞主星公轉一周，且與主星之間的距離僅為日地距離的5 % 。
  9. Some stars are so large that if the earth and the sun could be put ~ n any one of them, there would be space for the earth to go around the sun at its present distance

    有些星球大得可以把地球和太陽放在裏面，還有讓地球以現在這樣的距離圍繞太陽運轉的空間。
  10. I knew that it could not be our sun, that gave life to our earth, and that we were an infinite distance from our sun, but for some reason i knew in my whole being that it was a sun exactly like ours, a duplicate of it

    我知道，這不可能是那個養育過我們地球的太陽，我們距離我們的太陽無限的遠，但不知為什麼，我的整個身心卻感到，這個太陽和我們的那個太陽一模一樣，是我們太陽的復製品，是我們太陽的孿生兄弟。
