Astronomers have observed a small, massive object at the center of our Milky Way galaxy. A ring of material orbits this massive object; the ring has a diameter of about 15 light years and an orbital speed of about 200 km/s. A) Determine the mass of the massive object at the center of the Milky Way galaxy. Take the distance of one light year to be 9.461×1015m. I was able to get this it is 4.26×1037kg. B) Express your answer in solar masses instead of kilograms, where one solar mass is equal to the mass of the sun, which is 1.99×1030. I got this to it is 2.14×107 solar massesC)Observations of stars, as well as theories of the structure of stars, suggest that it is impossible for a single star to have a mass of more than about 50 solar masses. Can this massive object be a single, ordinary star? I got this it is no. D) Many astronomers believe that the massive object at the center of the Milky Way galaxy is a black hole. If so, what is its Schwarzschild radius? Express your answer in meters. E)Would a black hole of this size fit inside the earth's orbit around the sun? The mean distance from the sun to the earth is 1.5×1011m. Please solve part D and E. For part D please show equations and solve all the way through. I worked it twice and I am getting my answer wrong. I am afraid I am making a silly mistake
