Variations in the star's radial velocity?? that is, the speed with which it moves towards or away from Earth?? can be detected from displacements in the star's spectral lines due to the Doppler effect.

Chapter 16: Toward a New Heaven and a New Earth: The Scientific Revolution and the Emergence of Modern Society Chapter Summary In the Scientific Revolution, Western Europe disproved the idea of a geocentric universe and of the old Ptolemaic-Aristotelian view of the world and a new conception of the universe was born. New conception: the sun at the center of the universe, planets as material bodies revolving around the sun in elliptical orbits, infinite rather than finite world. Nicolaus Copernicus: heliocentric universe; Johannes Kepler: elliptical orbits of planets; Galileo Galilei: observed moon and sunspots with telescope = discovered universe is composed of material substance; Isaac Newton: law of gravity.
