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
