这样的距离应当会使母恒星的引力影响足够微弱，以致COROT9b能够保留距离自己几百万公里的稳定旋转卫星。
At that distance the host star's gravitational influence should be sufficiently weak that COROT 9 b could retain stably orbiting moons millions of kilometers from the planet.
虽然卫星的快速旋转足以将它们挤压成一个光滑的椭圆形，但它无法解释碟形中心的边缘。
While the moons' rapid rotation would be enough to squash them into a smooth oval, it can't explain the rim around the centre of the saucer shape.
我们的银河系实在庞大，吸引着数十个较小的星系环绕着它奔跑，恰似环绕巨大行星旋转的卫星。
Our galaxy is so huge that dozens of lesser galaxies scamper about it, like moons orbiting a giant planet.
