The first technique that allowed astronomers to find exoplanets involved radial velocity or wobble method.

Several methods for detecting exoplanets have been developed: Doppler measurements, transit observations, microlensing, astrometry, and direct imaging. Clever in- novations have advanced the precision for each of these techniques; however, each of the methods have inherent observational incompleteness. The most popular methods of discovering exoplanets are the transit method and the wobble method, also know as radial velocity. A few exoplanets have been discovered by direct imaging and microlensing. Until the launch of Kepler it was the method that had found the most planets. This technique is called the radial velocity or "wobble" method. Astronomers split up the visible light emitted by a star into a rainbow.
