The cluster is located 24.59 ± 0.13 kly (7.54 ± 0.04 kpc) [9] from the Galactic Center and is following an orbit through the Milky Way galaxy with a low eccentricity of 0.03 and an orbital period of 204.2 Myr. At present it is 23 ly (7 pc) below the galactic plane, and it will cross the plane every 29.4 Myr. [1]
