TON 618

 Every one might have know about Black Hole. Everything has a bigger and smaller. Similarly The largest black hole ever discovered was namely TON 618.

TON 618 is a hyperluminous, broad-absorption-line, radio-loud quasar and Lyman-alpha blob located near the border of the constellations Canes Venatici and Coma Berenices, with the projected comoving distance of approximately 18.2 billion light-years from Earth.

Distance to Earth: 10.37 billion light years

Absolute magnitude: -30.7

Coordinates: RA 12h 28m 25s | Dec +31° 28′ 38″

Apparent magnitude (V): 15.9

Distance: : 3.31 Gpc (10.8 Gly); (light travel distance); 5.59 Gpc (18.2 Gly); (present comoving distance);

Constellation: Canes Venatici

Redshift: 2.219

Diameter:

With a mass of 66 billion M☉, TON 618 has a Schwarzschild radius (the radius of a black hole based on its mass) of 1,949 × 10¹⁴ meters. That's a black hole with a diameter of 389.8 billion kilometers, or 242.2 billion miles!

More Info:

TON 618 is in the constellation Canes Venatici. This black hole was one of the very famous black hole and a supermassive black hole. 

Discovery Of TON619:

In 1970, a radio survey at Bologna in Italy discovered radio emission from TON 618, indicating that it was a quasar. Marie-Helene Ulrich then obtained optical spectra of TON 618 at the McDonald Observatory which showed emission lines typical of a quasar.
