黃金閱讀隕石篇 - 英檢

Paragraph 7: Earth is a target in a cosmic shooting gallery, subject to
random violent events that were unsuspected a few decades ago. In 1991 the
United States Congress asked NASA to investigate the hazard posed today by
large impacts on Earth. The group conducting the study concluded from a
detailed analysis that impacts from meteorites can indeed be hazardous.
Although there is always some risk that a large impact could occur, careful
study shows that this risk is quite small.
