The
Distribution of Globular Clusters
•Assume Globular Clusters orbit around center of galaxy
–Center of Globular Cluster distribution is 8.5 kpc in direction of Sagittarius
–We are about 2/3 of the way out to one side – so
“diameter” is approx. 25 kpc or 75,000 ly.
–Dust within the galactic plane fools us with respect to distribution of ordinary stars
