Q0906+6930 was the most distant known blazar[1] (redshift 5.47 / 12.2 billion light years)[2] at the time of its discovery in July, 2004.

The engine of the blazar is a supermassive black hole (SMBH) approximately 2 billion times the mass of the Sun[3] (the mass of the Milky Way Galaxy is around 1.5 trillion solar masses).

The event horizon volume is on the order of 1,000 times that of the Solar System.

With a redshift of 5.47,[1][2] light from this active galaxy is estimated to have taken around 12.3 billion light-years to reach Earth.

[2] But since this galaxy is receding from Earth at an estimated rate of 285,803 km/s[1] (the speed of light is 299,792 km/s), the present (co-moving) distance to this galaxy is estimated to be around 26 billion light-years (7961 Mpc).
