NGC 5897
NGC 5897
NGC 5897 is a globular cluster in the constellation Libra. This satellite of the Milky Way, which is quite remote with some 40,000 light years, has a diameter of more than 170 light years. It is an extremely loosely composed representative of his class, because it has a 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 8.7 arc minutes and a brightness of 8.6 mag.
