HD 189733b is a hot Jupiter - a planet similar in mass to Jupiter in our Solar System, but one that orbits much closer to its star, and so is much hotter.

HD 189733 b是一个炽热的木星——一颗和太阳系中的木星极为相似的行星，但是它绕行的轨道更接近与它的恒星，因此比木星更为炎热。

During this period of irregularity, which may have lasted millions of years, any rocky inner world sitting in the path of the hot Jupiter and its new orbit would have been obliterated.

这种不规则的时期可能已经持续了几百万年，在此期间，位于热木星原有轨道以及新轨道上的任何系内的岩石行星都有可能已遭毁灭。

Current computer models predict that hot-Jupiter planets-gas giants that orbit very close to their stars-could be only as dark as Mercury, which reflects about 10 percent of the sunlight that hits it.

当前的计算机模型预测：近距离围绕恒星运行的炽热的木星类行星(巨大的气体球)只能像水星一样暗，后者能反射照射到它上面的大约10%的太阳光线。
