A single supermassive black hole can contain 10% of its galaxy’s mass

At the center of many galaxies, supermassive black holes can weigh up to 10% of the entire galaxy’s mass. For a galaxy like the Milky Way, that would be billions of Suns packed into a region just a few times the size of our Solar System.

Despite their relatively tiny size compared to the galaxy, their gravity dominates the core, influencing star orbits, gas dynamics, and even galaxy evolution over billions of years. These cosmic giants show just how much mass can be concentrated in a single point in space.
