The planetary bodies of our solar system all tend to lie near this plane, since they were formed from the sun's spinning, flattened, proto-planetary disk.
太阳系内所有的行星成员的运行轨道都趋于这个平面，因为它们都是依据以太阳为轴心的平面轨道运行的。
A hole in the dust disk surrounding our solar system would tell alien observers there are planets here, a new simulation shows.
