What is the name of the supermassive black hole located at the center of the Milky Way?

Sagittarius A*

Sagittarius A* is a supermassive black hole at the heart of our galaxy, the Milky Way. It has a mass equivalent to about 4 million times that of the Sun. Black holes are objects so dense that nothing, not even light, can escape their gravity. Sagittarius A* is relatively quiet for a supermassive black hole, but observations of material approaching its event horizon provide crucial information about the nature of black holes and galaxy dynamics. The discovery that a supermassive black hole resides at the center of nearly every large galaxy has transformed our understanding of the universe.
