S5 0014+81 is a distant, compact, hyperluminous, broad-absorption line quasar or blazar located near the high declination region of the constellation Cepheus, near the North Equatorial Pole.
The object is a quasar, the most energetic subclass of objects known as active galactic nuclei, produced by the rapid accretion of matter by a central supermassive black hole, changing the gravitational energy to light energy that can be visible in cosmic distances. In the case of S5 0014+81 it is one of the most luminous quasars known, powering up light equivalent to over 1041 watts, equal to an absolute bolometric magnitude of -31.5.
If the quasar was at the distance of 100 light-years it would appear in the sky as bright as the Sun despite being 63 million times more distant. The quasar's luminosity is therefore about 3 x 1014 (300 trillion) times the Sun, or over 25 thousand times as luminous as all the 100 to 400 billion stars of the Milky Way Galaxy combined, making it one of the most powerful objects in the universe.
However, because of its huge distance of 12.1 billion light-years it is not visible to the naked eye and hence must be studied by larger telescopes. The central black hole of the quasar devours an extremely huge amount of matter, equivalent to 4000 solar masses of material every year.
