NGC 7006

NGC 7006 is a globular cluster located in the constellation Delphinus. It is one of the most distant globular clusters in the Milky Way galaxy, lying approximately 135,000 light-years from the Solar System. This extreme distance places it well beyond the galactic halo and makes it a valuable object for studying the outer reaches of our galaxy.

The cluster was discovered by William Herschel on September 7, 1784. It is designated as GCL 119 in the Galactic Catalog of Globular Clusters. NGC 7006 is a relatively sparse globular cluster, classified as a Shapley-Sawyer concentration class I, meaning that it is highly concentrated at its core. Its apparent magnitude is around 10.6, making it visible through moderately sized telescopes.

Studies of NGC 7006's color-magnitude diagram have revealed information about its stellar population and age. The cluster is believed to be very old, likely formed early in the Milky Way's history. Its location and composition suggest it may have been accreted from a dwarf galaxy or other external source. Further research continues to probe its properties and its role in understanding galactic formation and evolution.
