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
