Galactic center mass
WebBased on the resulting stellar orbits, the UCLA Galactic Center Group has settled (as we saw) on a gravitational solution that requires the presence of a supermassive black hole with a mass equivalent to 4.6 million Suns—all nestled within a space smaller than that occupied by our solar system. WebAstronomers can use the Sun's orbital motion to calculate the mass of the galaxy within a radius of 8.5 kpc from the Milky Way's center. The result is about 10 11 solar masses or 100 billion times the mass of the Sun. By using information from radio and optical surveys, we can plot the average circular velocity of material at a variety of different distances from …
