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。

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。

This common method in the planet-hunting world, called radial velocity, requires extremely precise measurements to detect a planet's gravitational pull on a nearby star.

这一行星寻找领域内的常见手段叫做径向速度法，需要极度精确的数据测量才能检测到行星对附近恒星的引力作用。
