Q0906+6930was the most distant knownblazar[1](redshift5.47 / 12.2 billion light years)[2]at the time of its discovery in July, 2004. The engine of the blazar is asupermassive black hole(SMBH) approximately 2billiontimes the mass of theSun[3](the mass of theMilky Way Galaxyis around 1.5 trillionsolar masses). Theevent horizonvolume is on the order of 1,000 times that of theSolar System.It is one of themost massive black holes on record.
Distance measurements[edit]
The "distance" of a far away galaxy depends on thedistance measurementused. With aredshiftof 5.47,[1][2]light from thisactive galaxyis estimated to have taken around 12.3billionlight-yearsto reach Earth.[2]But since this galaxy is receding from Earth at an estimated rate of 285,803 km/s[1](thespeed of lightis 299,792 km/s), the present (co-moving)distance to this galaxyis estimated to be around 26 billion light-years (7961 Mpc).[2]
