What is the diameter of the biggest black hole in the universe?
about 78 billion miles
So we have to look at one of the most massive of all supermassive black holes. It has a diameter of about 78 billion miles. For perspective, that’s about 40\% the size of our solar system, according to some estimates. And it’s estimated to be about 21 billion times the mass of our sun.
How big is NGC 4889?
125,000 light yearsNGC 4889 / Radius
How big is the biggest black hole in light-years?
53.5 million light-years
The largest supermassive black hole in the Milky Way’s vicinity appears to be that of Messier 87 (i.e. M87*), at a mass of (6.4±0.5)×109 (c. 6.4 billion) M ☉ at a distance of 53.5 million light-years.
How big does a supermassive black hole have to be?
2 to 3 solar masses
So, for a star with the same mass as our Sun, the Schwarzschild radius is about 3 km, or about 2 miles. In general, stars with final masses in the range 2 to 3 solar masses are believed to ultimately collapse to a black hole.
What is the largest spiral galaxy?
The largest spiral galaxy in the local universe could well earn the nickname “Godzilla Galaxy,” astronomers say, thanks to its truly gargantuan size. The galaxy, UGC 2885, is 2.5 times wider than the Milky way and hosts a trillion stars, 10 times more than Earth’s galactic home.
How old is NGC 4889?
300 million years old
Caldwell 35, also known as NGC 4889, is a galaxy that is truly far, far away — roughly 300 million light-years, or about 1,750,000,000,000,000,000,000 miles. That means the light from Caldwell 35 that reaches Earth today is 300 million years old.

What are the sizes of black holes?
A typical stellar-class of black hole has a mass between about 3 and 10 solar masses. Supermassive black holes exist in the center of most galaxies, including our own Milky Way Galaxy. They are astonishingly heavy, with masses ranging from millions to billions of solar masses.
