SMSS J215728.21-360215.1, commonly known as J2157-3602, is one of the fastest growing black holes and one of the brightest quasars known to exist as of 2018. The quasar is located at redshift 4.75[1], corresponding to a comoving distance of 25×109 ly from Earth and to a light-travel distance of 12.5×109 ly. It was discovered with the SkyMapper telescope at Australian National University’s Siding Spring Observatory, announced in May 2018. It has an intrinsic bolometric luminosity of 6.95×1014 L☉ (2.66×1041 W).[1][2][3][4][5]
