Scientists clarified the parameters of the “most gluttonous” black hole

(ORDO NEWS) — The superbright quasar SMSS J215728.21-360215.1 in the constellation South Pisces, which appeared 1.2 billion years after the Big Bang, is more than 12 billion light-years distant from Earth.

In the center of the quasar is the ultra-massive black hole J2157-3602 *, which increases by 1% every million years. Such rapid growth provides the “gluttony” of the object, which daily absorbs the amount of matter corresponding to one solar mass.

Giant black hole

The most accurate measurement methods have established that the mass of the black hole J2157-3602 * is 34 billion solar masses. To help you understand how much this is, we recall that the mass of the supermassive black hole Sagittarius A *, located in the center of the Milky Way, is about 7900 times less than the mass of J2157-3602 *.

It is worth noting that with such an impressive size, a giant black hole has other equally impressive parameters. For example, the Schwarzschild radius (event horizon radius) J2157-3602 * is at least 670 astronomical units (au), which is 17 times greater than the average distance from Pluto to the Sun, which is 39.5 au.

Black hole closest to Earth discovered is it dangerous

If we assume, based on recent data, that heliopause is at a distance of 100 AU from the Sun, more than six Solar systems would fit into the radius of the event horizon J2157-3602 *

There are even more

Of course, J2157-3602 * has fantastic parameters, but this is not the most massive black hole that science knows. In the center of the Holm 15A galaxy, which is 700 million light-years distant from Earth, is an ultra-massive black hole weighing about 40 billion solar.

At a distance of 10.4 billion light-years from us, there is the quasar TON 618, the core of which is a black hole with a mass of 66 solar masses.
