Part A = 4.26 * 10^37 kg
Part B = 2.14 * 10^7
Part C = no
Part D = 6.31 * 10^10 m
Part E = yes

Determine the mass of the massive object at the center of the Milky Way galaxy.
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 * 10^30 kg.
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?
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 Rs?
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 * 10^11 m.
