SDSS J0100+2802 (SDSS J010013.02+280225.8) is a hyperluminous quasar located near the border of the constellations Pisces and Andromeda. It has a redshift of 6.30,[1] which corresponds to a distance of 12.8 billion light-years from Earth and was formed 900 million years after the Big Bang.[2] And it appears to diverge at a velocity of 1.3782e+8 m/s. It unleashes an immense amount of power equivalent to 3×1041 watts, which corresponds to the absolute bolometric magnitude of -31.7 which is 4.3×1014 times the luminosity of the Sun, and 40,000 times as luminous as all of the 400 billion stars of the Milky Way galaxy combined. SDSS J0100+2802 is about four times more luminous than SDSS J1148+5251, and seven times more luminous than ULAS J1120+0641, the most distant quasar known,[1] although it is only less than fourth as luminous as HS 1946+7658, the most luminous quasar known. It harbors a black hole with mass of 12 billion solar masses[1] (estimated (1.24±0.19)×1010M according to MgII emission line correlations). This makes it one of the most massive black holes discovered so early in the universe, although it is only less than one fifth as massive as TON 618, the most massive black hole known. The diameter of this black hole is about 70.9 billion kilometres, seven times the diameter of Pluto's orbit.
