The Doppler technique can be used to obtain the orbital period, orbital distance, the orbital shape and the minimum mass of the planet. Doppler spectroscopy (also known as the radial-velocity method, or colloquially, the wobble method) is an indirect method for finding extrasolar planets and brown dwarfs from radial-velocity measurements via observation of Doppler shifts in the spectrum of the planet's parent star.. 880 extrasolar planets (about 21.0% of the total) were discovered using Doppler spectroscopy, as of February 2020. Turn off the drive and the star will drift west. Doppler spectroscopy is used to detect the periodic velocity shift of the stellar spectrum caused by an orbiting giant planet. Doppler: provide minimum masses; easier to detect large planets. astrometric measurements, Gaia should be able to detect the as-trometric motion of HD114762, even in the most unfavorable edge-on case.
