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。
Now, in addition to the hundreds of exoplanets discovered throughout the Milky Way, they've found six orbiting just one star: Kepler 11.
而现在，除了在银河系上下已发现上百个系外行星，他们在一个恒星周围就找到了6个，这个恒星就是开普勒11。
