Overview
HSC 891 is a poorly populated, moderately dense object of intermediate C3 quality. Its parallax locates it at a close* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the age parameter (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~0.91 kpc) differs significantly from the median photometric distance (~1.34 kpc).
