Unformatted text preview: planets, and estimate how much their orbits expanded or contracted. d. Assuming the starting orbital positions you calculated above, make a plot of the surface density in this minimum mass solar nebula. Be sure to use the original masses of the planets (as calculated in Problem Set 2). e. Discuss timescales for the formation of Uranus and Neptune in your new minimum mass solar nebula. Are there still problems? f. If you extrapolate your new MMSN, how much mass resides in the 10 AU region beyond Neptune. How does this compare to the mass of the present-day Kuiper belt? How does this compare with the mass that you calculated that Neptune need have scattered? Comments? 1...
