Antlia B (also known as Ant B) is a faint dwarf irregular satellite galaxy located around 72 kiloparsecs from NGC 3109, a small irregular galaxy located 4.3 million light years from Earth at the edge of the local group. Antila B has a complex mixture of old red giant branch stars over 10 billion years old and young blue stars only a few hundred years old. Despite Antlia B being rich in gas, Antlia B shows no evidence of active star formation.
