在晴朗的夜晚，当我们抬头仰望天空，有时会发现一个明亮的光点划破长空，飞驰而过，这就是流星。流星和地球一样，也是太阳系的成员。它在绕太阳运动的过程中，有时会被地球吸引，以极快的速度坠入地球大气层。根据天文观测，每天从宇宙空间坠入地球大气层的流星约有几十亿个 On a clear night, when we look up at the sky, we sometimes find a bright spot of light piercing the sky and speeding. This is the meteors. Meteor, like the Earth, is also a member of the solar system. It is sometimes attracted by the Earth during its movement around the Sun and crashed into the Earth’s atmosphere at an extremely rapid rate. According to astronomical observations, there are billions of meteors that fall into the Earth’s atmosphere every day from space.
