Terzan 8 is a globular cluster in Sagittarius. It was discovered by Agop Terzan in 1968. Like nearby Terzan 7, It is thought to be part of the Sagittarius Dwarf Spheroidal Galaxy.
Terzan 8 is a low-mass and metal-poor globular cluster. Uncharacteristic of globular clusters, Terzan 8 contains only one age group of stars. The reason for this is currently unknown. What is known is that the cluster formed in a satellite galaxy that has now been absorbed into the Milky Way, possible the Sagittarius Dwarf Spheroidal Galaxy.[3]
