**NGC 5466** is a [globular cluster](/source/Globular_cluster) of stars in the [constellation Boötes](/source/Bo%C3%B6tes_constellation). It was discovered by German-British astronomer [William Herschel](/source/William_Herschel) on May 17, 1784, and catalogued as H VI.9.[8] This large, dim cluster has an [apparent visual magnitude](/source/Apparent_visual_magnitude) of 9.2 and spans an [angular size](/source/Angular_size) of 9.0′.[4] It is relatively distant from the [Sun](/source/Sun),[3] about 52 thousand [light-years](/source/Light-year) (16.0 [kpc](/source/Parsec#Parsecs_and_kiloparsecs)) away,[3][9] and 53 thousand light-years (16.3 kpc) from the [Galactic Center](/source/Galactic_Center).[10]

## Observations

The [Shapley–Sawyer Concentration Class](/source/Shapley%E2%80%93Sawyer_Concentration_Class) of NGC 5466 is XII.[1] This is a loose cluster with an unusually low central density compared to other globulars with similar luminosity.[11] It is located at a high galactic latitude and thus displays negligible [reddening](/source/Extinction_(astronomy)) from [interstellar dust](/source/Interstellar_dust).[11] The cluster has a core radius of 1.43′±0.10′ and a half-light radius of 2.3′±0.07′. The King tidal radius is 238.0 ly (72.98 pc).[3]

Observation of the distribution of stars in the cluster shows the impact of mass segregation, with heavier objects sinking toward the center. This is a dynamically young cluster that is just starting to evolve.[12] An [isochrone](/source/Stellar_isochrone) fit to the cluster yields an age estimate of 12.15±0.11 billion years.[6] Other age estimates range from 12.2±0.9 to 13.57 Gyr, depending on the method.[9][13] It has an extremely low [metallicity](/source/Metallicity).[6]

In 2006, a long [tidal stream](/source/Tidal_stream_(astrophysics)) was detected stretching from this cluster,[14] perhaps reaching as far as 45° to 60° across the sky.[15][16] It has a combined mass estimated as 4.0×103 [*M*☉](/source/Solar_mass).[3] The width dispersion of the stream is 1.31°±0.24°, corresponding to a physical width of 1,200 ± 220 ly (367 ± 67 pc) at the distance of the cluster.[3] The presence of a tidal tail suggests the cluster has been strongly disrupted due to gravitational interactions with the [Milky Way](/source/Milky_Way) galaxy.[11] At some point, this stream may have been tidally disrupted by the [Large Magellanic Cloud](/source/Large_Magellanic_Cloud).[16]

A total of 97 [blue straggler](/source/Blue_straggler) stars have been identified in this cluster, which show a mild central peak in distribution.[17] In 2019, it was reported that a candidate hot [white dwarf](/source/White_dwarf) had been discovered orbiting a [blue straggler](/source/Blue_straggler) star in the outskirts of NGC 5466. This was the second such pair discovered in a globular cluster.[18] Three short period [eclipsing binaries](/source/Eclipsing_binaries) have been found along with six [SX Phoenicis variables](/source/SX_Phoenicis_variable).[19][20] This was the first globular where a blue straggler eclipsing variable was found.[12] The cluster is host to the brightest-known anomalous [Cepheid variable](/source/Cepheid_variable), designated V19.[21][22]
