Globular cluster in the constellation Libra

NGC 5897 The globular cluster NGC 5897 imaged with an amateur telescope. Observation data (J2000 epoch) Class XI[1] Constellation Libra Right ascension 15h 17m 24.40s[2] Declination −21° 00′ 36.4″[2] Distance 24.1 kly (7.4 kpc)[2] Apparent magnitude (V) 8.52[2] Physical characteristics Radius 6.3' x 6.3'[3] Metallicity [Fe/H] = −2.04±0.15[4] dex Other designations GCl 33, C 1514-208[2] See also: Globular cluster, List of globular clusters

**NGC 5897** is a [globular cluster](/source/Globular_cluster) in the [constellation](/source/Constellation) [Libra](/source/Libra_(constellation)). This satellite of the [Milky Way](/source/Milky_Way), which is quite remote (located about 41,000 [light years](/source/Light_year) away), has a diameter of over 170 light years. With its [Shapley–Sawyer Concentration Class](/source/Shapley%E2%80%93Sawyer_Concentration_Class) of XI, it has very low star density even in its center.[3]

The stars of the cluster have only 0.91% of the [Sun's](/source/Sun) metallicity,[5] while the abundance of elements produced by the [alpha process](/source/Alpha_process) is roughly 5 times larger.[4] This means that the cluster formed in a time before the galaxy formed a disk and spiral arms. However, some of the stars are apparently younger, indicating multiple star-forming epochs.[4]

NGC 5897 has a diameter of 12.6 arcminutes and an [apparent magnitude](/source/Apparent_magnitude) of 8.5.
