NGC 6453 is a globular cluster approximately 37,000 light-years away from Earth[3] in the constellation of Scorpius. The cluster is located approximately 1 kpc (~3,260 light-years) from the Galactic center[4], which results in confounded view of the cluster from the Solar System due to many intervening clouds of cosmic dust.[5]
The cluster measures nearly 8' across, and it's brightest stars are no brighter than 14th magnitude.[5]
Observational history
NGC 6453 was discovered by John Herschel on June 8, 1837[1][5], while he was observing from the Cape of Good Hope in South Africa.[6] He included the cluster as "h 3708" in his 1864 Catalogue of Nebulae and Clusters of Stars, and Danish-Irish astronomer John Dreyer later added the cluster to his New General Catalogue as object number 6453.[5] Dreyer described the cluster as "considerably large, irregularly round, pretty much brighter (in the) middle, round".[5]
