Is there a black hole at the center of our Galaxy?

Yes, there is a very large black hole at the center of our Galaxy. It has a mass of about three million suns and is very far from Earth at a distance of about 24,000 light-years. Huge black holes are thought to occur naturally at the center of most large galaxies and many have already been detected. The black hole which lies at the center of our Galaxy is much too far away to be of any danger to Earth.
