More than 200,000 quasars are known, most from the Sloan Digital Sky Survey. All observed quasar spectra have redshifts between 0.056 and 7.54 (as of 2017).
Although quasars appear faint when viewed from Earth, they are visible from extreme distances, being the most luminous objects in the known universe.
