最后，月球作为地球独特而巨大的卫星，在稳定地球旋转轴的倾角方面发挥了关键作用。
Finally, Earth's unique and massive satellite, the Moon, plays a crucial role in stabilizing the obliquity of Earth's rotational axis.
地球独特而巨大的卫星——月球，在稳定地球旋转轴的倾角方面发挥了关键作用。
Earth's unique and massive satellite, the Moon, plays a crucial role in stabilizing the obliquity of Earth's rotational axis.
这些卫星处在平稳旋转的地球上空，几乎可以对全球的所有地区进行稳定的扫描，因此能很好地完成气象观察、通讯以及其它任务。
Such satellites—maintaining their steady sweeps as the earth revolves beneath them—cover all parts of the globe and hence are ideal for weather observation, communications and other tasks.
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.
