Again, you may enter '2000 AC6' in the 'Object' field. After pressing the key, the position, the speed and direction of the apparent motion of the asteroid will appear.

同样的，你可以在目标区域输入"2000 AC6"，然后按键，位置、速度及视运动的方位角将会显示出来。

During its examination of the asteroid ida , the galileo spacecraft discovered a second object , dactyl - the first confirmed satellite of an asteroid

伽利略号观察小行星伊达时，竟然发现伊达有一颗星。这颗被命名为达克图的星，是首颗被确定的小行星星。

Right now, if an Earth-bound asteroid were discovered, we have the technology today to send a spacecraft to an asteroid to act as a gravity tractor, or to impact the asteroid to alter the space rock's trajectory.

现在，如果地球的小行星被发现，我们今天的技术传送飞船小行星作为重力拖拉机，或影响小行星改变空间岩石的轨迹。

Space scientists will now study the data taken by Rosetta of asteroid Steins in an effort to better understand its composition, origin, and why the asteroid reflects light so well.

太空科学家将分析罗塞塔号为斯坦斯所拍摄的影像数据，以确定它的组成、起源以及为何它有这么好的反光能力。

In support of the asteroid-impact model, it had been argued that the gradual cooling of the average ocean temperature would enable progressively smaller asteroid impacts (which are known to occur more frequently than larger impacts) to cool the Earth's climate sufficiently to induce ice-cap growth and reversals.

为了支持行星带影响模型，提出了这样的一个观点，这个逐渐的变凉，平均海洋温度变凉，这个逐渐的变凉会使得递进式地更小的行星带的影响（这个行星带被认为更加频繁地发生比起更大的影响）去降低地球的温度，降低地球的温度怎么样呢？充足到导致IC的增长和R。

Since there are some disadvantages, such as magnitudes, reference systems and difficulties in observing an asteroid during its motion in its whole orbit, etc., when the asteroid is observed simply by means of the meridian or photograph methods, a new method for observing asteroids with a lower latitude meridian circle and a CCD measuring device is proposed according to the conditions of the geographic latitude of the Yunnan Observatory which can be used to observe the whole orbit of an asteroid.

考虑到单纯用子午方法或照相方法对小行星进行观测存在着因星等、定标星系统，以及难于在小行星运行全轨道上进行观测等方面的不利因素，在本文中，根据云南天文台能观测小行星全轨道的地理纬度条件，提出利用低纬子午环与CCD测量装置相配合，并利用低纬子午环直接提供的定标星，在一个统一的基本仪器系统中，通过对小行星在全轨道上均匀分布的观测，获得高精度的小行星观测资料，以便得到更准确的星表零点改正。

The inner asteroid belt looks identical to ours in terms of material, and it orbits at 3 astronomical units from Epsilon Eridani — the same distance between the sun and the rocky asteroid belt between Mars and Jupiter. An astronomical unit equals the average Earth-sun distance of 93 million miles, or about 150 million km.

内围小行星带中的物质看起来跟我们太阳系的小行星带一模一样，在3天文单位的距离上环绕着恒星& E 波江&——这个距离跟火星和木星之间的小行星带到太阳的距离也一样。1天文单位等于地球跟太阳之间的平均距离，相当于9，300万英里，或者15，000万公里。
