the measurement of stellar parallax of nearby stars provides a fundamental baseline in the cosmic distance ladder that is used to measure the scale of the universe. parallax measurements of nearby stars provide an absolute baseline for the properties of more distant stars, as their properties can be compared. measurements of the radial velocity and proper motion of stars allows astronomers to plot the movement of these systems through the milky way galaxy. astrometric results are the basis used to calculate the distribution of speculated dark matter in the galaxy.
