Exoplanets detected by radial velocity, also known as the Doppler method or the radial velocity method, is a technique used to identify exoplanets by observing the gravitational influence they have on their host stars. This method takes advantage of the Doppler effect, where the light emitted by a star shifts in wavelength depending on its motion relative to an observer.
