詹金斯表示，这一趋势将会继续，因为开普勒——2009年3月发射以寻找类似地球的外星球——和其他望远镜持续不断的传来数据。

That trend will likely continue, Jenkins said, as data keeps pouring in from Kepler — which was launched in March 2009 to search for Earth-like alien planets — and other telescopes.

“尽管这颗行星不在可居住带，该发现还是让人兴奋无比的，因为它表明了更多类似发现的可能性，”开普勒项目科学家道格拉斯·哈金斯说道。

"Although this planet is not in the habitable zone, the exciting find showcases the kinds of discoveries made possible by the mission," said Kepler program scientist Douglas Hudgins.

开普勒计划已经发现了大约4500颗系外行星，其他星球都不如452b这般和地球相似。 但是詹金斯表示，还有50%的星球是我们没有观测到的。

The Kepler Mission has found around 4,500 exo-planets, although no others as similar to Earth as 452-b, but Mr Jenkins said there were still 50 per cent of planets we cannot yet see.
