NGC 5897 is a globular cluster in the constellation Libra.

With its Shapley–Sawyer 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 metallicity,[5] while the abundance of elements produced by the alpha process is roughly 5 times larger.

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 of 8.5.
