This is tiny compared to the Milky Way itself, which is 100,000 light-years wide and 1,000 light-years thick. The central massive object of the Milky Way is a supermassive black hole of about 4 million solar masses, which is called Sagittarius A*. The Milky Way has 100 million stellar-mass black holes, with 90 million having less than 30 times the mass of the sun and 10 million having 30 times the mass of the sun or more.3 Sources
