Aleksander Wolszczan and Dale Frail found the first confirmed example of one these bodies using pulsar timing, but a more prolific method for their detection is the radial velocity method, which looks for changes in spectral lines due to the Doppler effect. A different method examines changes in brightness of a star due to these objects' transits.

A different method examines changes in brightness of a star due to these objects' transits. Both pulsar timing and radial velocity take advantage of small perturbations in the motion of a star due to one of these orbiting masses. Name these objects found both inside and outside the Solar Systems, examples of which in the solar system include Mars and Jupiter.
