It has been disrupted and consists of a comoving star-stream with about 25,000 stars. The stars are in an elliptical orbit near their apocenter (furthest point) about 8,500 light years distant in the Milky Way. The stars have similar age and metallicity. The stars were discovered in spectra from the Large Sky Area Multi-Object Fibre Spectroscopic Telescope.[1][2] References1. ^{{cite web|last1=Nowakowski|first1=Tomasz|title=Disrupted globular cluster found in the constellation of Draco|url=http://phys.org/news/2015-12-disrupted-globular-cluster-constellation-draco.html#nRlv|website=Phys.Org|accessdate=18 December 2015|date=18 December 2015}} {{star-cluster-stub}}2. ^1 2 3 4 5 {{cite arxiv|eprint=1512.05090|last1= Vickers|first1= John J.|title= LAMOST 1: A Disrupted Satellite in the Constellation Draco|last2= Smith|first2= Martin C.|last3= Hou|first3= Yonghui|last4= Wang|first4= Yuefei|last5= Zhang|first5= Yong|class= astro-ph.GA|year= 2015}} 2 : Moving groups|Draco (constellation) |
