Based on your answer above, how would you explain the difference between the orbital velocity curve for our Solar System and the orbital velocity curve of the MWG$?$ Be explicit about the differences you see in these. Does the velocity of orbit actually decrease as you move away from the center of mass in the MWG$?$ Or$,$ does the orbital velocity curve of the MWG show that the velocities increase? Was that expected for you? Why? What law did we originally use to predict that the velocity would decrease as we moved away from the center of mass?
