告诉大家一个好消息,天文学家宣布:地球被太阳系小行星撞击而毁灭的可能性,比以前的估计小得多。天文学家过去的计算结果显示:太阳系中约有200多万颗直径超过1000米的小行星。地球如果遭到其中一颗撞击,将造成全世界四分之一的人口死亡,而且这种小行星会“定期”访问地球,机率约为每隔1亿年一次,21世纪就可能碰到一回。为此,忧心忡忡的科学家未雨绸缪,四处搜寻地球附近的"可疑分
To tell everyone the good news, astronomers announced that the possibility of the Earth being destroyed by the impact of the solar system asteroid is much smaller than the previous estimate. Astronomers’ past calculations show that there are more than 2 million asteroids with a diameter of more than 1,000 meters in the solar system. Earth’s impact on one of these planets will cause a quarter of the world’s population to die, and this asteroid will “repeatedly” visit Earth with a probability of about once every 100 million years and may touch in the 21st century. To one time. To this end, worrying scientists plan ahead and search for suspicious points near the earth.
