NGC5139 (Omega Centauri)
NGC5139 is a globular cluster approximately 15,800 light years away from us. It is estimated to be about 12 billion years old and contains several million stars. It is the largest known globular cluster associated with our galaxy. It's so packed with stars that near its center they are around 0.1 light years apart. The nearest star to us is Proxima Centauri at about 4.24 light years. Relative to our solar system, 0.1 light years lies between the orbit of Pluto and the Oort Cloud (about 1 light year out).
