NGC 5897
NGC 5897 is a globular cluster in the constellation Libra. This satellite of the Milky Way, which is quite remote, has a diameter of over 170 light years. With its Shapley–Sawyer Concentration Class of XI, it has very low star density even in its center.
The stars of the cluster have only one per cent of the sun's metallicity, which means that they were formed in a time before the galaxy formed a disk and spiral arms.
NGC 5897 has a diameter of 12.6 arcminutes and an apparent magnitude of 8.5.
