2) Plot the Messier object distances in the semi-log plot. Use different symbols for each of the categories or use the category numbers themselves in the plot.


3) What details of the plot strike you as especially pertinent? Remember the semi-log plot extends over 6 orders of magnitude. Include a one page narrative in your discussion.
