NGC 2210 is aglobular cluster located in theLarge Magellanic Cloud, in theconstellation Dorado. It is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. It was first discovered by astronomerJohn Herschel on January 31, 1835.[5] In 2017, Rachel Wagner-Kaiser and a group of researchers from theUniversity of Florida discovered that NGC 2210, as well as five other globular clusters located in the Large Magellanic Cloud were of roughly the same age as some star clusters found in theMilky Way, and that NGC 2210 is roughly 11.6 billion years old.[3] It was first imaged by the Hubble Space Telescope in 2023.
