A decent wobble, though, requires a massive planet, so the wobble method does not favour the discovery of smaller, Earth-sized objects.
尽管最近一次的摇晃需要巨大的行星，因此摇晃法并不利于发现较小的、地球般大小的天体。
The planet, called VB 10b, was discovered using astrometry, a method inwhich the wobble induced by a planet on its star is measured preciselyon the sky.
这颗行星，VB 10b，是用天体测量学的方法，精确测量它的恒星在空中的受迫摆动而发现的。
