Episode Details

Astronomers following asteroid activity in space estimate there is a very small chance an object large enough to destroy a whole city could strike Earth in 2032. 

在太空估计中，遵循小行星活动的天文学家很少有一个足够大的物体摧毁整个城市，可以在2032年撞击地球。 

But space agency officials say even if such an asteroid keeps heading on a path toward Earth, the world is now much better-equipped to defend itself against such a threat. 

但是航天局官员说，即使这样的小行星不断前往地球的道路，现在，世界已经准备好捍卫自己的威胁。 

The American space agency NASA recently estimated there was a 3.1 percent chance that asteroid 2024 YR4 would hit Earth on December 22, 2032. That is the highest probability predicted for such a large space rock in modern times. 

美国航天局NASA最近估计，小行星2024年将在2032年12月22日袭击地球有3.1％的机会。这是现代如此大的太空岩石所预测的最高概率。 

Richard Moissl is head of the European Space Agency's (ESA) planetary defense office. While recognizing the risk the asteroid could present, he told the French news agency AFP people should not panic over such predictions.

 理查德·莫斯尔（Richard Moissl）是欧洲航天局（ESA）行星防御办公室的负责人。 他告诉法国新闻机构法新社，人们不应对这种预测感到恐慌。 

Astronomers have noted that the more data they gather, the odds of a direct asteroid hit are expected to keep rising over time. However, scientists say at a certain point the odds will likely drop down to zero. 

天文学家指出，他们收集的数据越多，直接小行星命中的几率预计会随着时间的流逝而不断上升。 但是，科学家说，在某个时刻，赔率可能会下降到零。 

Moissl said he thinks it is important to remember that even in the unlikely event the probability keeps rising to 100 percent, the world is "not defenseless." 

莫斯尔说，他认为重要的是要记住，即使在不太可能的情况下，概率不断上升到100％，世界“没有防御”。
