The Mariner spacecraft found that the surface of Mars, as well as that of its two moons, is pitted with impact craters formed by meteoroids falling in from space.
水手号宇宙飞船发现火星表面，还有它的两个卫星表面，都有由太空坠落的流星体造成的陨石坑。
The Sun is the hub of a huge rotating system consisting of nine planets, their satellites, and numerous small bodies, including asteroids, comets, and meteoroids.
太阳是一个巨大的旋转系统的中心，这个旋转系统由九大行星、它们的卫星和无数的小天体组成，包括小行星、彗星和流星体。
It's from meteoroids that we get meteors and meteorites.
我们从流星体中得到流星和陨石。
If a batch of meteoroids comes from the same comet, the meteor shower is formed.
如果一批流星体来自同一颗彗星，形成的就是流星雨。
Consequently, MIPS allows astronomers to study the production of meteoroids by comets whose orbits do not cross the Earth's path.
因此，MIPS使天文学家得以研究与地球轨道不交汇的彗星产生的流星体。
Such particles, called meteoroids, are the same size as those that appear in meteor showers when they enter the Earth's atmosphere.
这些被称为“流星体”的微粒，和在流星雨时落入地球大气的流星具有同样的大小。
Thermal stress in meteoroids by aerodynamic heating is calculated for the ideal case of an isotropic, homogeneous, elastic sphere being heated at the surface with a constant heat transfer coefficient.
