Supermassive Black Hole

(black hole with a mass of millions to billions of solar masses)

A Supermassive Black Hole (SMBH) is a large Black Hole, often in the center of a Galaxy. A black hole is considered "supermassive" if its mass is on the order of millions (or hundreds of thousands) of solar masses or more. The largest observed as of 12/2012 is on the order of 20 billion solar masses.

Such large black holes are considered the energy source for an Active Galactic Nucleus. Such a black hole has been detected in the center of the Milky Way by observing the tight orbits of stars around it.

A Supermassive Binary Black Hole (SMBBH) is two orbiting SMBHs. They are thought to result from Galaxy Mergers.
