The new discovery, based on data from NASA's planet hunting Kepler spacecraft, makes the Kepler-11 system the fullest exoplanetary system known.

这项根据 NASA 的开普勒行星探测航天器发回的数据得出的新发现，让开普勒 11 星系成为了最完整的地外行星系统。

Their presence, sizes, and masses have been determined by carefully watching the planets dim the light of Kepler-11 while transiting or crossing in front of the star itself.

它们的存在、大小和质量已经通过仔细观察这些行星在经过或穿过开普勒11跟前时让其光芒减弱的程度得到了确定。

The Kepler 11 solar system is interesting not just because it has more planets than any we've observed outside our own, but also because it's extremely compact.

开普勒 11 恒星系很有意思，这不仅是因为它是除我们自己的太阳系以外，已观测到拥有行星最多的星系，也因为它非常的紧凑。

And in a paper published by Nature to coincide with NASA's announcement of its candidates, that discovery was trumped six times over by an analysis of the most populous putative system, Kepler 11, 2, 000 light-years from Earth.
