Overview
HSC 2885 is a sparse, very dense object of high C3 quality. Its parallax locates it at a close distance, near the mid-plane, affected by low extinction. It is catalogued as a metal-poor, young cluster, but with a large variance across recent sources for the age parameter (see Parameters). It was recently reported in the literature.
