Rubin suggests that asteroids' heat could have derived from collisions between asteroids.───鲁宾认为，小行星的热量可能来自小行星之间的碰撞。
Roids are, for the most part anyway, they are just smaller bits of asteroids and comets.───在很大程度上，Roids 只是小行星和彗星的小碎片。
So to talk about where meteorites come from, we need to talk about comets and asteroids.───那么讲到流星体从何而来，我们就需要讨论下彗星和小行星。
Asteroids that are just a few feet or meters across are called asteroids. We see them as meteors when they enter Earth's atmosphere.───那些直径只有几公尺的小行星统称为流星体，当它们进入地球大气层后就形成流星。
Ceres turned out to be just one of many asteroids orbiting between Mars and Jupiter, rather than a proper planet.───谷神星结果只是众多绕着火星和木星的卫星中的一颗，而并非什么行星。
Asteroids - something from the sky comes closer and closer and then hits 'Home'! Have the metaphors 'hit home' with you yet?───小行星-来自天空的某种东西越来越接近来临了，于是就跟‘家’碰撞上了！就你而言‘碰撞家’仍然有暗喻的说法？
Even after working and optimizing the asteroids for a week until they rendered at a great performance, the physics were still way too slow.───用了一个星期的时间来优化小行星的，并获得了不错的渲染效果，物理过程的运行依然缓慢。
If all such asteroids turn out to be harmless windmills, it will have been a wasted effort.───如果所有的行星都被证实是毫无害处的风车时，那就是白花力气了。
Asteroids are minor planets, most of which circle the sun in a region known as the asteroid belt, between the orbits of Mars and Jupiter.───小行星是较小的行星，它们中的大部分在火星和木星轨道间的小行星带中环绕太阳运行。
Generally, it is very difficult to find asteroids smaller than about 1 kilometer in diameter using photographic techniques.
It has also found two Centaur family asteroids in orbits that cross the orbits of several of the Jovian planets.
These appear to be pieces of carbonaceous asteroids.
Many of the known asteroids are small enough to blow up on entering the atmosphere.
Comets and carbonaceous asteroids of the appropriate energy disrupt too high, whereas typical iron objects reach and crater the terrestrial surface.
Extraction of helium-3 from the surfaces of asteroids is not likely to compare with that from the Moon.
Asteroids, also known as " minor planets ", are numerous in the outer space.
Comets and asteroids are subjects for Chapter 14.
Comets differ from asteroids in composition in that comets contain abundant water ice, and possibly other ices as well.
