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 1.5x10^5 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]
Discovery

VVV CL001 was discovered by using the VISTA Variables in the Via Lactea (VVV) survey. It has several aims such as resolving the three-dimensional structure of the Milky Way galaxy by precisely measuring the distribution of RR Lyrae, Cepheids, and red clump stars.[5] Another aim of the VVV survey is to accurately measure the physical parameters of known globular clusters and search for new ones. It was this which discovered VVV CL001.[4]
