NGC 6717 (also known as Palomar 9) is a globular cluster in the constellation Sagittarius, and is a member of the Palomar Globular Clusters group. Palomar 9 was discovered by William Herschel on August 7, 1784.

NGC 6717 is located at a distance of 7.1 kpc from the Sun and 2.4 kpc from the Galactic centre, which places it in the bulge of the Milky Way. It has a dense core, which may indicate that it has undergone a core collapse.

NGC 6717 is a Globular Cluster in the Sagittarius constellation. NGC 6717 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year.

William Herschel discovered this cluster and cataloged it as H III.143. He described it as a very faint round nebula and apparently thought it was a cluster with nebulosity. It was first recognized as globular cluster by Per Collinder in 1931.

NGC 6717 is a Globular Cluster located in the constellation of Sagittarius in the southern hemisphere. NGC 6717 is called NGC 6717 in the New General Catalogue (NGC). This catalogue is a list of deep space objects compiled by John Louis Emil Dreyer in 1888 to update John Herschel's earlier work.
