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. To measure distances in the universe, we will need to construct what is commonly referred to as a "cosmic distance ladder". All of them rely on detecting a planet's effect on its parent star, to infer the planet's existence. In the case of the Meade that would be at the 25th division mark on the linear scale.
