Feb 2, 2016 at 22:37 comment added CuriousOne Sagittarius A* has about 4.3 million solar masses. The total mass of stars, gas clouds and dark matter in the galaxy between us and this black hole is much, much larger than that, probably by a factor of 10,000 or so. Therefor we are not actually rotating this supermassive black hole but the center of mass of this matter distribution. One could even say that it's not Sagittarius A* that captures the galaxy, but it's the galaxy that is holding Sagittarius A* captive in its gravitational minimum. All Sagittarius A* "can do" is to locally feed on a few stray stars and hydrogen once in a while.
