Deep Sky

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