LAMOST 1 is a star cluster in the constellation Draco. 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.[2][1]
