TON 618 is a Quasar - described as a very distant and extremely luminous quasar—technically, a hyper-luminous, broad-absorption line, radio-loud quasar—located near the North Galactic Pole in the constellation Canes Venatici. It likely contains one of the most massive known black holes, estimated to be 66 billion times the mass of the Sun.
Usually the size of a black hole is given by it’s mass - measured in solar masses. But you may be wanting to know the radius of the event horizon - which also describes the size of a black hole. The event horizon of the super massive black hole in TON 618 would be 198 billion kilometers.
TON 618 is a very distant and extremely luminous quasar—technically, a hyperluminous, broad-absorption line, radio-loud quasar—located near the North Galactic pole ,in the constellation canes venatici. It likely contains one of the most massive known black holes, perhaps weighing in at 66 billion times the mass of the sun.
It is expected to be 10.4 billion years old.The size of the broad-line region can be calculated from the brightness of the quasar radiation that is lighting it up.From the size of this region and the speed it's orbiting, the law of gravity reveals that the mass of the black hole in TON 618 is 66 billion solar masses.The event horizon in TON 618 will be 198 billion km .
Hope you understand it's actual vastness by visualization.
It's event horizon is 238 billion kilometers.. Fastest spacecraft new horizon takes 10yrs to travel to Pluto.. So that space craft takes 460yrs to travel to the edge of Ton618.. Yu can place 46 solar systems end to end.
