WebBy determining the distribution of the globular clusters, Harlow Shapley was able to determine the diameter of the galaxy, and the distance to the galactic center. Procedure . Using the polar graph in Figure 1, plot the galactic longitude versus distance for the globular clusters in Table 1. The Sun is at the center of this polar graph. WebThe distance can be determined from knowledge of the distance of the sun from the galactic center, about 8 kpc. Using Θ HI gives a measure of the mass interior to the point r and thus the cumulative mass of the Galaxy. Recent work has extended this to include large molecular clouds, which also orbit the galactic center.
