The supermassive black hole dubbed J2157 is only one step short of the largest black hole in the universe Abell 85 which has a mass of 40 billion suns.
If the Milky Ways black hole wanted to grow that fat, it would have to swallow two-thirds of all the stars in our galaxy, quipped Christopher Onker, the lead author of the study published in Monthly Notices of the Royal Astronomical Society.
According to him, how much a black hole can eat depends a lot on how big they already are. In this case, the black hole is already so huge to begin with, which is why it can sustain the diet of one sun a day. The analysis shows that the black hole is growing by 1% every one million years.

Wolf believes that if this black hole was at the centre of the Milky Way, it would appear in Earths skies 10 times brighter than a full moon. It would appear as an incredibly bright pin-point star that would almost wash out all of the stars in the sky, he said.
It would make life nearly impossible on Earth with the huge amounts of X-rays that emanate from the massive black hole.
