"It's great to have entered the era that discovering super-Earths is routine," added Seager, who was not involved in the HARPS research.

没有参与HARPS研究的西格尔补充道：“很庆幸我们进入了一个以发现超级地球为日常工作的伟大时代。”

In total, the results suggest that planets ranging from Earth-sized to about four times Earth's size - so-called "super-Earths" - may be more common than previously thought.

这一结果表明，大小从与地球相仿到四倍于地球(又称为“超级地球”)的所有行星，总数可能比以前想象中要多得多。

She predicts that the same process could take up to hundreds of millions of years for super-Earths, or exoplanets that are at least twice as big as Earth and are just now being discovered.

她预测，同样的过程对于“超级地球”或者系外行星(才被发现的、至少是地球的二倍)可能要花上数亿年。

They were also able to extrapolate whether those super-Earths were likely to be orbiting in the habitable zone around the star.

They are named super-Earths because they are more massive than the Earth but less massive than Uranus and Neptune (which are about 15 Earth masses).

Based on their findings, they were able to extrapolate that more of the stars also probably had super-Earths, based on gravitational analyses, though the planets were not definitively detected.
