Overview
HSC 869 is a sparse, very dense object of intermediate C3 quality. Its parallax locates it at a relatively close* distance, near the mid-plane, affected by moderate extinction. It is catalogued as a metal-poor, young cluster (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~1.17 kpc) differs significantly from the median photometric distance (~2.13 kpc).
