VVV CL001 is a globular cluster located around 8.22 kiloparsecs from Earth in the constellation of Sagittarius.[1] It is the most metal poor globular cluster discovered around the Milky Way. [2] It is an old globular cluster with an age of 11.9 billion years. VVV CL001 is likely an ancient relic that was left behind by a past galactic merger by a massive galaxy early in the evolution of the Milky Way galaxy.[2] It has a mass of 1.5×105 solar masses.[3]
It may be in a physical binary with another globular cluster known as UKS 1 however it is still being decided if they are an actual binary or have similar radial velocity.[4]
