The globular cluster, pictured here, contains roughly 100,000 stars.
These stars formed together and are gravitationally bound. Stars orbit
center of the cluster, and the cluster orbits the center of our Galaxy.
This is one of the finest clusters in the sky with stars
at magnitude 5.7 measuring 23' across corresponding physical diameter
of 125 light years. M-5 lies high above the galactic plane
25,000 light years away. Because it is so bright, M-5 is
to the naked eye as a 'star' with dark skies.
