It is the optically-brightest quasar in our sky, and one of the closest with a redshift, z, of 0.158. A luminosity distance of DL = 2.44 Giga light years may be calculated from z. It is also one of the most luminous quasars known, with an absolute magnitude of -26.7. Its mass has been measured to be 886 ± 187 million solar masses through broad emission-line reverberation mapping.
