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] 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] This makes it one of the most massive black holes discovered so early in the universe, although it is only less than a third as massive as S5 0014+81, 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.
