最后，科学家测量了由于行星的引力拖拉而产生的恒星摆动，这就是径向速度。
2
Radial velocity, also known as the Doppler wobble technique, involves searching for wobbles in a star's light that indicate the gravitational pull of an orbiting planet.
径向速度法，也被称为多普勒摆动技术，用于搜索恒星光线的摆动，它显示出来自轨道上运行的行星的万有引力。
3
The new planets were detected by measuring "radial velocity," or how fast a star wobbles depending on the gravitational pull from nearby planets.
新的行星是靠测量“径向速度”，或者恒星在周围行星的万有引力下摇摆的速度检测出来的。
