Moving swiftly through the atmosphere, meteoroids are heated rapidly by friction . 流星体在快速穿过大气层时，因磨擦而迅速加热。
If the meteoroids are bunched together, the number of meteors seen varies from year to year . 如果流星体聚集在一起，则每年看到的流星数都不一样。
Perhaps the outer part of the moon was heated to the melting point by intense meteoric bombardment . 也许月球外层曾被流星体猛烈的撞击而加热到熔点。
Most of them were formed by the impacts of meteorites 布满陨石坑，大部分是由流星体所造成。
Meteoroids are small particles in space with size similar to grains of sand .宇宙充塞著沙粒大小的流星体。
Performance analysis for spacecraft shield structures against meteoroid and space debris 航天器微流星体及空间碎片防护结构性能分析
A solid body , moving in space , that is smaller than an asteroid and at least as large as a speck of dust 流星体活动在空间的固体天体，比小行星小，至少与尘埃一样大
The inflatable spars , for example , will not remain rigid for long because of the inevitable micrometeoroid impacts 举例来说，可膨胀伸出的帆桅，由于无法避免微流星体的撞击，因此无法长久保持坚硬的状态。
Life - bearing meteoroids and dust particles would be exposed to the vacuum of space , extremes in temperature and several different kinds of radiation 带有生命的流星体与尘粒，还会暴露在宇宙的真空、极端的温度与数种不同的辐射之下。
