Astronomers have observed a small, massive object at the centerof our Milky Way Galaxy. A ring of material orbits this massiveobject; the ring has a diameter of about 11 light-years and anorbital speed of about 200 km/s.
determine the mass MM of the massive object at the center of theMilky Way Galaxy. Give your answer in kilograms.Give your answer insolar masses (one solar mass is the mass of the sun).
Observations of stars, as well as theories of the structure ofstars, suggest that it is impossible for a single star to have amass of more than about 50 solar masses. Can this massive object bea single, ordinary star?
Many astronomers believe that the massive object at the centerof the Milky Way Galaxy is a black hole. If so, what must theSchwarzschild radius RSRSR_S of this black hole be?
Express your answer in meters.
Would a black hole of this size fit inside the earth's orbitaround the sun?
