OK, and there was another announcement along with the recalculated orbit of Gliese 581 D.
除了重新測算Gliese 581 D的軌道還有一個通告。
That was the discovery of another planet in the system, Gliese 581 E.
那就是在那個星系又發現了另一個行星，Gliese 581 E。
Compared with other exoplanets, its mass is quite small, only about twice that of Earth.
和其他的外星星球相比，它的質量很小，只是地球的兩倍。
Student: So, it Gliese 581 E a more earth-like planet?
學生：那Gliese 581 E是個和地球更類似的行星嗎？
Professor: Well, we have to consider its orbit.
教授：我們得考慮它的軌道。
Gliese 581 E orbits its host star in a much shorter period of time than the other planet in the system, meaning it’s very close to the star, and therefore too hot for water, for an ocean.
Gliese 581 E 環繞它的寄主星運行的時期比該星系其他行星的要短，也就是說它離恒星非常近，因此太熱而不會有水，不會有海洋。
However, the fact that it’s relatively close to the size of Earth, small, in astronomical terms, that was pretty exciting.
但是，它和地球的大小相對接近，按照天文學術語來講，比較小，這個事實非常令人興奮。
It’s impressive that we have the technology to detect it and it bodes well for future research.
我們有探測它的技術非常令人欽佩，而且這對未來的研究是個好兆頭。
Who knows what we’ll find the more we search.
誰知道我們再多搜尋一下會發現什么呢。
